Hello,

We had problem like yours before.
Please send us following info from your box:
# uname -a
# cat /proc/meminfo
# cat /proc/cpuinfo

If the problem will appears again, we will be appreciate you for "sysrq" report.
To enable sysrq reports run:
# sysctl -w kernel.sysrq=1

Then when your box will lock (like you described), please run:
# echo "t" > /proc/sysrq-trigger
This log "showTasks" report into /var/log/messages
# echo "m" > /proc/sysrq-trigger
This log "showMem" report into /var/log/messages

Then we will be able to exam /var/log/messages file you send.

Thank you for cooperation
Best Regards

Hello,

I think i have found out the Problem:

If is set an cpu limit for the hsphere-vps servers who are running on this server (all vps servers had an 10% cpu limit) the server crashes!
If i set the cpu-limit on all vps-servers to 0 (no limitation) all works fine!


any idears?

regards
Chris

Hello,

Thank you for reporting us the situation.
We will check the CPU limit issue and let you know results.
However all virtual servers on our test box are CPU hard limited and not crashed.

Hello,

Please, configure netdump on your VPS hosts to log all crashes.

Read more about netdump configuration at:
http://forum.psoft.net/showthread.php?p=89359#post89359

We need more log information to investigate the problem.

Best regards
