Subject: Google's mm problems

Hi, I've been taking a look on a mm problem that Ben Smith of Google posted
a couple of weeks ago. As it stands, Google can't use 2.4 yet because all
known flavors of 2.4 mm fall down in one way or another. This is not good.

The kernel that comes closest to working is 2.4.9. After running the test
application below for about 30 seconds, kswapd takes over and cpu utilization
goes to 100%. With a dual processor system the system remains usable
(because kswapd can't take over two cpus at the same time, however much it
would like to). The test application does run to completion, taking about
20% more real time and 95% more cpu than it should.

Other kernels show worse behaviour. Ben has checked them, I haven't yet.
Ben reports that they all lock up so that applications make no progress,
except for linux-2.4.13-ac4 which locks up with 3.5G but not with 2G.
According to Ben, the linus kernels after 2.4.9 (Andrea) lock up hard so that
power cycling is required, while control can be recovered on -ac (Rik)
kernels eventually by killing the application.

I took a look at this and was able to reproduce the problem easily on a 2.4.9
kernel, dual cpu, 2 Gig memory, using a procedure described below.

The application, written by Ben, goes through a loop mmaping a number of
large files, in this case 2 (with 2 Gig) and mlocking them. So the effect is
to allocate a lot of memory and free it. This works fine until free memory
runs out and freeable memory has to start being recycled. After a while,
most memory ends up on the active list and kswapd cpu utilization hits 100%.

Earlier, Andrea suggested trying madvise instead of mlock, and the results
are pretty much the same. (Which could be a clue.)

I found that the first obvious problem is, kswapd is never sleeping. I was
able to reduce cpu utilization to 35% easily by ignoring the result of
try_to_free_pages in kswapd, so that kswapd always sleeps after doing its
work. This sort of makes sense anyway, since in a heavily loaded state the
synchronous mm scanning does just as good a job as kswapd, and unlike
kswapd, does terminate after a known amount of scanning. This trivial
change change is obviously just a bandaid.

I've run out of time to work on this just now since I have to get ready for
ALS. The next step is to find out why kernels other than 2.4.9 have trouble
with this application. This includes both Rik and Andrea mm variants. So
I'm posting my results so far and a method for reproducing the problems.

The application uses a little over 8 Gig of test data on disk, created by
the following bash script:

for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19;
do dd if=/dev/zero of=/test/chunk$i count=6682555 bs=64; done

} else {
printf("Load (%s) succeeded!\n", filename);
}
mlock_slot(i);
close(fd);
}
printf("sleeping...\n");
while(1) sleep(5);
}

If it works flawlessly it will complete its work in about 20 X 18 seconds = 6
minutes, then sleep. On 2.4.9 it gets bogged down in kswapd after about 30
seconds as soon as the program has eaten its way through all the 'virgin'
memory and memory starts to be recycled. This causes it to take about 10
minutes to complete, and kswapd usage stays at 100% when the program sleeps.

On a subsequent run, the application will drive kswapd to 100% cpu
immediately, which is understandable because 99% of memory remains in cache.
This cache memory can be freed by putting the /test/ directory on a separate
partition and umounting it, which restores the system to a relatively
pristine state.

Profiling the kernel shows me that the cpu hogs are refill_inactive_scan,
page_launder, and pagemap_lru_lock contention, in that order. I suspected
that kswapd is never sleeping, so I applied this patch:

--- ../2.4.9.clean/mm/vmscan.c Wed Aug 15 05:37:07 2001
+++ ./mm/vmscan.c Tue Oct 30 16:15:52 2001

+ if (!do_try_to_free_pages(GFP_KSWAPD, 1) && 0) {
if (out_of_memory())
oom_kill();
continue;

Which just ignores the result of do_try_to_free_pages and allows kswapd to
sleep normally, even when it thinks it hasn't achieved its free memory
target. This reduced the steady-state cpu usage to about 35%, still very
unimpressive but no longer a DoS. With this patch in place, cpu usage drops
to about 18% when the program sleeps, so some of the cpu is being hogged by
do_try_to_free_pages on the kswapd path, and a roughly equal amount by
do_try_to_free_pages on the synchonous alloc_pages path.

Ben confirmed my results on his machine but observed that my patch did not
have much effect with 3.5 Gig in the machine instead of 2 Gig. So we know
that the badness scales with memory size.

With my patch in place, a profile during the steady state looks like this:

The stext_lock suggests that lock contention is excessive. However, ordinary
scanning is the real cpu hog.

At this point I ran out of time and didn't pursue the obvious question of why
so much more scanning than necessary is being done. Clearly,
refill_inactive_scan and page_launder aren't reaching their targets, but why?

Questions remain as to why Rik's mm is more heaviliy DoSed than 2.4.9, and why
Andrea's locks up completely. I'll be available if anyone wants to talk more
about this, and in a couple weeks I'll return to it if the problem survives
that long.

Rik, Andrea, enjoy ;-)

Subject: Google's mm problems with 2.4.13 and 4G of memory

I got a Dell powerEdge something with 4G of memory locking up pritty
hard when Danial Phillips test program hits chunk 9:

mlocking at 401bf000 of size 1048576
mlock took 12.181794 seconds
munlock'ed 5999e000
munmap'ed 5999e000
Loading data at 5999e000 for slot 1
Load (/mnt/sdb/sven/chunk9) succeeded!
mlocking slot 1, 5999e000
mlocking at 5999e000 of size 1048576


And nothing. It's a vanilla 2.4.13 kernel and Mandrake 8.0.

If I run the program up to like chunk 3 and send an interrupt it
doesn't free up the memory unless I umount the file system.

Please suggest idea on how to fix it. I have this system to abuse for
several days.

Not freeing up the memory until umount is not a bug, it's normal. The
(cache) memory is supposed to be freed up when it's needed for something more
important.

The discussion right now is about whether the mm is supposed to be able to
handle more than 50% mlocked memory or whether that's a user bug.

(I think we should be able to mlock >90% of memory, but there isn't general
agreement on this. The question is not whether it's possible, but whether
there's a real need for applications to be able to do this.)

Please stay tuned.

Andrea suggested that this might be a mlock bug and someone else
pointed out that madvise instead of mlock exhibits similar behaviour.
So I looked at this code and this patch looks obviously correct:

This assignment is redundant and it is not protected by any locks.
As far as I can see vma->vm_mm->page_table_lock is supposed to protect
modifications of vma->vm_flags. If this is true we probably need this
as well:

I doubt that this is the reason for the google memory problems, but

I'm pretty sure at this point that it's just poor balancing between zones. To
test this, Ben tried it highmem config'ed off and ran without problems (2/2G
user/kernel split).

With some in house code, on 2.4.14-pre8 I'm still getting some
unwanted swapping after filling up the cache that i'm not getting with
the 2.4.14-pre6aa1 kernel of a 4G system. With pre8 if fills up the
memory with cache and does some minor swapping, on pre6aa1 it fills up
the memory with cache and happily works.

Subject: 2.4.>=13 VM/kswapd/shmem/Oracle issue (was Re: Google's mm problems)

We're seeing an easily reproducible problem that I believe to be along
the same lines as what Google is seeing. I'm not sure if Oracle's SGA
(shmem) can be mlock()ed, but I'm guessing there's a state analogous to
Solaris' ISM. We're seeing this on a 4GB machine with HIGHMEM/HIGHMEM4G
set, using 2.4.1{3,4,5-pre1}.

The machine in question has one 99% active Oracle shadow process, with
kswapd eating about 17-20% CPU at all times. Per the top listings
below, Oracle is set to use a ~840M SGA. Interactive performance is
poor, behaving like moderate to severe swapping. A higher SGA increases
the severity of the problem -- 1.4GB seems to cause the machine to run
away and hide more or less permanently.

However, when a remote machine begins to copy a ~20MB file to this
machine via scp, the following top screen displays and the machine is
essentially frozen for a significant period of time (roughly 15 minutes
to two hours):

12:22am up 1 day, 35 min, 1 user, load average: 7.23, 4.35, 4.27
85 processes: 79 sleeping, 6 running, 0 zombie, 0 stopped

It looks like all quasi-active processes begin to "use" 100% system CPU
time. When the machine recovers 15-120 minutes later, the load has shot
up to >17 and the memory state seems unchanged. kswapd reappears at
70-80% CPU usage and slowly drops back down to an oscillating 20-90%
range. Swap usage continues to slowly creep higher:

3273 root 18 0 896 868 744 R 0 3.4 0.0 5:49 top

The issue gets better and worse over time without a specific period.
Other kinds of load on this type of machine and kernel seem fine, from
heavy compilation to a development platform for dozens of heavily-active
developers, NFS, etc.

A secondary issue is that kswapd before this hang event is eating 20-90%
more CPU than I think it should :) especially given Oracle's static SGA
that fits well within RAM. I understand that the quantitative swap
usage could be quite normal based on page age, but it's slightly
worrying that so much swap is being used, given that the page cache is
2.5GB.

This machine is an HP LH6000r (6-way Xeon) with 4GB of RAM (minus the
700MB that HP needs for hot-swappable PCI. I hate HP.) I've seen this
since 2.4.13, but didn't try anything between 2.4.9 and 2.4.13
exclusive. Currently running is 2.4.15-pre1 with Marcelo's vmscan
patch. I know it won't be "baptized", but it does seem to slightly
reduce the severity and length of the hang state.

Basically, this problem makes it impossible to run Oracle on Linux,
which is really a massive problem from our point of view. If someone
could show me how to provide more useful information or further debug
this problem, I would greatly appreciate it. This includes specific
alternate kernels, or perhaps without HIGHMEM4G or HIGHMEM.

I've attached some various stats etc below just to cover bases. This
example is not a pristine 2.4.15-pre1, due to the long-standing IO-APIC
issues and various other VM-unrelated patches, but the issue also
reproduces on pristine versions of 2.4.1{3,4,5-pre1}.

Thanks much,

[SNIP]

Oracle is a horrendous memory hog.
Looks like it's getting more bloated with each next release.

If I will start some seriuos database programming,
I will try PostgreSQL first... it is at least Open Source,
we can see what's inside.

Whee, looks like you guys really willing to resolve this...
Pity I can't do anything for you. Let's hope some VM folks will be
interested.

FYI: yes, that's the same problem. After some debugging I found the
exact reason of the bug, and as Daniel claimed a few weeks ago it is
really a VM problem, not an mlock problem. And it's one thing that I
didn't noticed while rewriting the VM, so it is reproducible on all 2.4
kernels out there, no matter what VM is in them. The kswapd infinite
loop that can trigger with the -ac VM when all the ZONE_DMA is
unfreeable (now fixed in mainline with classzone) have nothing to do
with this google problem, kswapd is right here to spend cpu time, the
bug is not kswapd activation.

I just sent Ben (at Google) a patch that fixes the problem completly for
me and for him and I'll try to release the real fix in the next days.
(so far it's a dirty workaround, that is just usable fine in their and
my memory configuration but it's not general purpose yet, but it's been
more than enough to proof my theory so far and I've in mind how to fix
it properly, tomorrow I hope I will implement it).

Ok I think I've misunderstood classzone then.
As I understand it, it prevents looping in ZONE_NORMAL when ZONE_DMA has
memory free,
and looping in ZONE_HIGHMEM if ZONE_NORMAL or ZONE_DMA have memory free.
Can you please explain how it also solves the ZONE_DMA problem ?

Thanks for looking into this -- I really mean it. I'm looking forward
to the patch and how it compares to the others I've received. ;-)

Again, good work, and thanks to all,

correct.

> Can you please explain how it also solves the ZONE_DMA problem ?

It also solves the ZONE_DMA problem with the ->need_balance trigger in
combination with the classzone logic.

With classzone in combination with the need_balance kswapd will never
ever waste time trying to balance a never used classzone.

If all your hardware is PCI nobody will make an allocation from the
ZONE_DMA classzone and so kswapd will never loop on the ZONE_DMA, as
instead can happen with -ac as soon as the ZONE_DMA becomes unfreeable
and under the low watermark (and "unfreeable" of course also means all
anon not locked memory but no swap installed in the machine).

We don't fallback to ZONE_DMA anymore? (good)

we still fallback on the ZONE_DMA, otherwise mem=17m wouldn't boot :)

what we don't do is to try to balance the dma zone if nobody is asking
memory explicitly from the dma zone [isa users].
