Zitat von Dariush Pietrzak <[email protected]>:

Just out of curiousity i use my kernel crash-test setup to test with
"stress" and "bonnie". I simply use the OpenVZ-Kernel with two
container (ubuntu-10.04) and let one run stress and the other
bonnie. The load is at 15 but the machine is humming along since
around 4 hours...
 With such low load we also couldn't crash it in timely matter.
With lightly loaded machines we endured months without crash.

I use this:
stress -c 22 -i 24 -m 8 -d 20 --hdd-bytes 10G
and this:
while (true)
 do
 bonnie++ -d /fs/v/bonnie/ -c 8 -b -f -u root
 echo next
done
 in parallel, I don't even have to run it inside containers.
(test machine is single 4-core Xeon E5320, with 4G ram and two 146G raid 1s
joined by lvm. With loadavg 50-80 we get crashes after few hours).

So i tried loading the kernel harder. With a load of about 48 it was still stable, if i raise the number for c,i,m,d even more, the OOM killer jumps in and from that point the whole machine freeze, but does not panic???

Regards

Andreas
