Thank you very much, I decided do not remove the limits but rather adapt the needed values manually.

But, please help me a little bit: What is the best (i.e. empiric) way to adopt the limits according to the "failcnt" value? It seems that just adding this value to the soft/hardlimit isn't enough...

What I do: I have written a small awk-script which monitors the sum of the failcnt-column in /proc/user_beancounters and if this value is >= 0 (i.e. some hosts have insufficient resources) send the output via cron.

I have a VE with the following content:

privvmpages       68769      90280      67536      71632         97

(and

PRIVVMPAGES="87536:91632"

in the config).

This means that this value is just ~100 too low; what to I do?

vzctl set 201 --privvmpages 87536:91632 --save

and restarting the VE. As you can see, I add 10000 (!) although only 97 are needed. But some time after restarting: same result. I adjusted the limit a few times now but failcnt becomes always nonzero for this specific limit after some time. So, what I am doing wrong?

There are other values in other VEs where I have the same problem, e.g.:

kmemsize        5122700   11059046   11055923   11377049       1434

And, one other thing. If I stop a VE, the entries in /proc/user_beancounters are not removed (only after some time). Why? This is especially problematic when I want to correct the limits, do "vzctl 201 restart" and check if the problems have gone.

I hope you can follow me Wink

Regards,
divB
