Can anyone tell me what this is?
16:00:09 mailserver kernel: Uhhuh. NMI received for unknown reason 31.
16:00:09 mailserver kernel: Dazed and confused, but trying to continue
16:00:09 mailserver kernel: Do you have a strange power saving mode enabled?
16:00:34 mailserver kernel: Uhhuh. NMI received for unknown reason 21.
16:00:34 mailserver kernel: Dazed and confused, but trying to continue
A coworker put a script on a server which loads up quite afew arrays
with pre-set values and then compares the values against arrays. As soon as he
kicked off the script I got alot of these in my log files. Not much longer and the
machine crashed hard.
Quad proc P3-550
16Gigs of RAM
Kernel: 2.4.22-rc2-ac3
CONFIG_HIGHMEM64G=y
CONFIG_HIGHMEM=y
Anyone have any thoughts or know what this means? Do I have a HIGHMEM
problem?

Possible bad RAM.

We ran "memtest" on the machine over the weekend and it completed 3
times without any problems. Know a better or different test?

Write 0x80 out port 0x70, and hope nobody accesses the RTC. This
will (should) disable the NMI line. Then see if the error messages
go away. If they do, it's a real NMI and you really do have bad
RAM somewhere. If they don't, your motherboard is getting glitched
either by bad design or something plugged into a slot that doesn't
have the correct timing specs.
If everything works, in spite of the NMI, just comment out the
kernel printk() and cross your fingers.

You might try to enable all the tests, addresses and set the
cache to be always on in memtest. Typical keys pressed is:
c - 1 - 2 - 2 - 3 - 3 - 3
Another is goldmemory, which is fairly the same in default setup
as memtest with above config, but shareware, not gpl.

I ran some tests Richard gave me which said it wasn't bad ram but a bad
motherboard. I just upgraded to 2.4.22-bk10 and it ran MUCH better,
able to use all 16Gigs happily for quite some time until a couple of the
processes started finishing then it gave the NMI's en mass, guess it
couldn't shove them off to the log server in time.
I'll try the below just to make sure but this is getting odd.
