Description Tim Waugh 2004-09-29 10:46:23 UTC

Description of problem:
Three times this month (twice this week) I have had to reboot this
uniprocessor AMD Duron because the machine will quite suddenly (within
the space of a minute or two) go into a swap frenzy.  When this
happens, no progress is observed at all.  I can't switch virtual
consoles.  I can't log in remotely.

Alt-SysRq-E (to SIGTERM all tasks) eventually stops it, but at that
point nothing will display on the screen and sshd is also dead, so I
have to reboot anyway.

Version-Release number of selected component (if applicable):
kernel-2.6.8-1.541

How reproducible:
Don't know how to reproduce it, but it happens enough to be really
annoying.

Comment 1 Tim Waugh 2004-09-29 18:35:31 UTC

This just happened *again*.  This time I was burning a CD using
cdrecord and suddenly the machine became completely unresponsive.  The
disk was in constant use.

It has happened before while burning a CD.  Perhaps it's related to
that? (It's also happened when I'm not doing that.)

Comment 2 Arjan van de Ven 2004-09-29 18:39:29 UTC

hmm audio cd by chance ???

Comment 3 Tim Waugh 2004-09-30 08:26:17 UTC

Yes.

Comment 4 Tim Waugh 2004-09-30 16:30:51 UTC

This just happened again, but I was not burning a CD at all.  Two
local users logged in, Mozilla, Firefox, Evolution and GIMP were all
that was running.

Comment 5 Tim Waugh 2004-09-30 19:14:11 UTC

Happened again with even lighter load.  This time I was running
2.6.8-1.521 (latest FC2 kernel) to try to avoid the problem.

I'll try 2.6.8-1.590.

Comment 6 Tim Waugh 2004-10-04 11:34:01 UTC

FWIW, I haven't seen this again yet with 2.6.8-1.590.

Comment 7 Tim Waugh 2004-10-10 10:58:03 UTC

Still haven't seen this again.  I only switched from 1.590 (to 1.603)
today.  Looks like this might be fixed?

Comment 8 Tim Waugh 2004-10-14 13:18:31 UTC

Pretty sure this is fixed now.
