Last night, one of your production machines got wedged, I caught a lot
of kernel: VM: do_try_to_free_pages failed for ... for a whole range of
processes, among them ypbind, klogd, syslogd, xntpd, cron, nscd, X,
master (Postfix super daemon), pvmd3, K applications and so on, I was
unable to log in via ssh, someone on-site has finally reset that machine
this noon to bring it back online.
How can I get rid of those do_try_to_free_pages lockups? That box
exports root file systems for some SparcStation 2 that are used as X
terminals, so it's pretty important I keep that box running.
Should I try the most recent 2.2.19-pre?
The machine is a pentium-MMX with 64 MB RAM with a kernel 2.2.18 that
has these patches/updated drivers (none VM related AFAICS):
IDE 2.2.18.1209
I?C 2.5.4
LM_Sensors 2.5.4
DC390 2.0e7
ReiserFS 3.5.28

Almost everybody (including me) who have seen that problem seem to
have had it fixed with Andrea Arcangeli's VM-global-7 patch
(ftp://ftp.kernel.org/pub/linux/kernel/people/andrea...).

Yes, Andrea's VM-global-7 is included in pre2.

2.2.19pre2 should resolve that problem

I'll give that a try. Thanks to you and Ville Herva for replying.

If you still see the problem with Andrea's VM global patch (you can get
just that one patch from ftp.kernel.org/pub/people/andrea), try cutting
JOURNAL_MAX_BATCH in half. This will lower the amount of memory reiserfs
is willing to pin in one transaction...
