Before doing so, I tried to test memory with a help of memtest86+. I did so, and memtest could not find any problem. Since then... I cannot reproduce the problem anymore neither with 072.10 nor with 068.8 :-/. I tried it many times. The system boots normally, vzctl stop|start|restart doesn't lead to panics. So, my system have been working for an hour or so. However, I see a lot of kernel messages like the following. It seems this is well known problem (redhat bugs #739467, #678486, #558190) but in my case stack traces are different and contain nfs related functions. I see these messages on 3 of 8 of my servers. If it is a bug, I'll report them to bugzilla with more details.
