fork: Cannot allocate memory after each command

[postcd]

Hello, this is an OpenVZ VPS with Debian Linux.

it is 128MB RAM and 256MB with burst. But after each command i see fork error. Can you please help to discover where the issue lies and how i can remove this error without upgrading RAM which seems to be alot of free? Thank You

I was adviced to check bean counters because im hitting some of the limits there:
cat /proc/user_beancounters
If yes, if there are fail counts (failcnt), then i need to ask my VPS provider to raise that limit.
