Hello everyone,
So far I've been able to handle all OpenVZ problems by myself but this time I got stuck and can't find answer via google (maybe I am looking wrong).
Single process does not show high usage in ps aux, but in top it shows 99% cpu usage and whole node get frozen, pings stop to get back (to the main node and VPSes).
When I will try multiple times I finally get connected via SSH and can kill the process and everything goes back to normal.
I have wrote a script that will detect such processes and kill them, but that does not solve problem 100%.
Seems that CPU limitations are not working somehow. Any idea where to look for root cause of the problem?
