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
