Hello,

Quote:


- it is possible that a misconfiguration in VEs can crash the server?


A misconfiguration mustn't crash the server. But it may drastically decrease performance.

- it may be a bug in OpenVZ kernel?


Don't hesitate to make a new bug report if any bug is found.

My HN crashes every weekend at different times, this weekend it crashed 2 times... and my customers are not really happy


We have to be provided with textual logs describing the crash in detail.
A serial console might be very helpful to get the full crash output.

I think I have seen on the console an output like an "oops" (http://wiki.openvz.org/Oops) but I'm not sure that the logs do not see anything abnormal, except this:

tail /var/log/messages


These messages indicate that out of memory was invoked

http://linux-mm.org/OOM_Killer

But I cannot see any crash related things.
If it is an out-of-memory situation that bothers your customers so much you may have to set up user_beancounters parameters more accurately. The best thing I can suggest you is to read an article describing UBC in general and in detail.
