Hi Philipp,

cat /proc/user_beancounters:
  uid  resource           held    maxheld    barrier      limit    failcnt
       privvmpages      381463     384383     384000     393212        821


Look, you simply got a "privvmpages" failcounters, which means that your Container allocated too much memory and hit its limit (allocated != used).

Well, i think you have to understand what application inside a Container requires so many RAM (381463*4096=1562472448 ~ 1.5 Gb is quite a lot) and decide if this is normal or not for that application.
And if you decide that this is normal, should just have to increase the privvmpages limit.

Hope that helps.

And talking about CPUUNITS... well, just leave it by default at least you get a stable and working system. Smile

Good luck!

vzctl set 202 --privvmpages 768000:786424 --save


This will provide your Container 3 Gb of RAM for allocation.

You've got "numproc" failcounters.
Please, increase "numproc" limits.

If your problem is solved - please, report it!
It's even more important than reporting the problem itself...
