hello, sirs!
I've installed the nagios with nagvis plugin and from time to time it stops to respond, while i still can vzctl enter into this machine.
i receive this message in /var/log/messages
Warning: The check of host '****' could not be performed due to a fork() error: 'Cannot allocate memory'.
here is the conf of this container:

seems like there is a memory leak somewhere... why the hell it wants to use 4,4 GB of ram ? 
emmm... seems like i've got it. i gave to VEs total guaranteed memory more, than i have physically... how can i null those failcnt out, so it would be easy to monitor the changes?
