I have problem with some servers. Sometimes server hangs up and in kernel log I couldn't find any kernel panic or others information about problem.
Below could be found spec:
OS: Debian 7.8
Kernel: 2.6.32-openvz-042stab105.6-amd64
CPU: Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz
I've checked and that it isn't connected with CPU, because I've observed similar problem on other CPU:
Intel(R) Xeon(R) CPU E3-1246 v3 @ 3.50GHz
What should I check ? I have zabbix monitoring on every problematic server and from graph it is ok for me (any cpu jumps, any ram jumps, etc)
In kern.log sometimes could be observed:

@Mar 8 18:32:21 gs92 kernel: imklog 5.8.11, log source = /proc/kmsg started.
I forgot mention that while server is not responding, ping works but other service (ssh, apache, mysql) don't

so have you checked is it working fine?
what is the load on disks?
where containers are created? in /home?
you have to investigate and find if there is a problem in server. if not then submit a bug report.

What should I have checked ? I have no idea. That problem is connected with many type of servers.
Load of disk is it ok in the moment when server hangs up, please see graph: http: //oi59.tinypic.com/358t3k5.jpg
vz containers is created on /home part:
# ls -l /var/lib/vz
lrwxrwxrwx 1 root root 8 Mar 26 09:28 /var/lib/vz -> /home/vz
I've tried many methods and I can't find solutions on that problem
