Debian 6 with OpenVZ crashes
type: item
description: Hi @all, I've installed Debian 6.0.4 with 2.6.32-5-openvz-686 Kernel on my HP DL760 G2. My CTs work really fine, but sometimes the hole box stalls and you have to switch off and on. I reduced the memory to 16 GB, but the same problem appears. It also doesn't look like a hardware problem, because the unpatched Debian kernel and ESXi runs without any problems. I also have ssh sessions which showed me: top: no heavy load messages: no entries user_beancounters: no entries After rebooting the box everything is fine again until the next crash. Are there some more logs to look for the error? Thanks Daniel

Still... I assume it doesn't have 64 bit processors installed? If it does, you might want to switch to the 64 bit kernel, as it's better tested. What are your symptoms of the "stall", let's assume it's deadlocked processes - you should find out what the processes are blocked on (e.g. using the top 'WCHAN' column). You can get some state info out of the kernel with: echo 'T' > /proc/sysrq-trigger echo 'W' > /proc/sysrq-trigger etc. Probably best to open a Debian kernel bug, as the OpenVZ team don't support the Debian kernels. You might want to try the official OpenVZ kernels, and see if the problem still occurs. Tim. -- South East Open Source Solutions Limited Registered in England and Wales with company number 06134732.
