It is obvious from this output, that this VE requires much more resources then
available for it.

Check whether failcnt columnt counters are increasing over the time
to understand what resource shortages your VEs do experience.
>From this output it is clear that it has shortages of
kmemsize, tcprcvbuf and numfile resources.

You can increase those using the command:
# vzctl set <VEID> --<resource> <new-value>

(also check for vzsplit tool)

Thanks,
Kirill
