next in thread | raw e-mail | index | archive | help
I'm running 4.1-S as of August 23, and ever since I updated to 4 I've been
having
a strange problem with load averages. The machine I'm on is a small
workstation
that is usually very quiet (mosly used as an x-terminal and e-mail
destination).
At least three times, I have had load averages suddenly jump to over 1 and stay
there. This is very unusual for this machine. The only time I get load
averages
that high normally is a buildworld/installworld. top shows one running process
(itself) and that the machine is 90+% idle. The only way to fix things seems
to
be to reboot the machine. The load average profile after the jump looks just
like normal, except everything is +1 from there. I haven't been able to figure
out how to reproduce the problem.
Any suggestions on how I could troubleshoot this the next time it happens are
extremely welcome.

p.s. Here's dmesg output:
