Hi! I have a problem with my OpenVZ VPS. Here is my current processlist:
root@GleSYS-vps:~# ps auxf

As you can see only syslog, sshd and init is running. Here is what user_beancounters report:

As you can see, despite the fucked up line breaks, is that privvmpages is 99201 which I think is a lot for the number of processes I have running.

Is this a bug in OpenVZ or can there be a logical explanation of the problem?
