Hello,

It's possible the "leak"

Yes, it might be a leak. Moreover, you said that

Same code runs without problems on non openvz kernels 2.6.22 25 27 for months
|
So, let's try to find out if it's indeed a memory leak.

Now it's happening again, apache process is using 100% cpu, I can't enter the vps beancounters bellow

Looks like you have to adjust CPUUNITS/CPULIMITS on the HN. You may read about them in OpenVZ user's guide

Oomguarpages exceeded barrier value, so this is likely the reason why a process inside that VE was killed.

Do you have a single VE on the HN? If no, please show the full user_beancounters output.
Next time this issue will occur try to stop the problem VE (hope CPULIMIT/CPUUNITS adjustment will allow to do that) and look at the user_beancounters again. There should be no usage when VE is stopped. Please, also look at the slab state. If the consumption value is decreased. And show please /proc/slabinfo output after and before stopping the problem VE.
