Kernel VM problems.
Hello Debians.
I seem to have some Kernel VM problems, but I'm not sure why.
Sometimes I see my machine nearly freezing, and then becoming good
after a minute or two.
In the logs I get up to several hundred lines like these:
Aug 20 18:22:13 pc89225 kernel: VM: do_try_to_free_pages failed for gpm...
Aug 20 18:22:16 pc89225 kernel: VM: do_try_to_free_pages failed for gpm...
Aug 20 18:22:18 pc89225 kernel: VM: do_try_to_free_pages failed for gpm...

Aug 20 18:22:55 pc89225 kernel: VM: do_try_to_free_pages failed for syslog-ng...
Aug 20 18:22:57 pc89225 kernel: VM: do_try_to_free_pages failed for gpm...

Aug 20 18:22:57 pc89225 kernel: VM: do_try_to_free_pages failed for init...
Aug 20 18:22:57 pc89225 kernel: VM: do_try_to_free_pages failed for syslog-ng...
etc., etc. ...
(it usually repeats the same message more often than this example).
I do see ``kernel: VM: do_try_to_free_pages failed for <something>...''
in the logs from time to time, but they are most often only one or two
at a time, and they aren't felt at all.
My kernel is a selfcompiled (with make-kpkg) 2.2.17pre6 kernel from the
kernel-source deb, no extra patches.
I usually happens when I fetch mail with fetchmail, invoking exim,
procmail and lbdb in the process, but it seems to be all running
programs that's affected by it.
It's annoying, though it only happens once or twice per week, I'd like
if there were some kind of fix.
I hope someone more knowledgeable than me knows what's going on, it
might be a suptle misconfiguration in my kernelconfig ...
Kind regards
Morten
