OK - i found some strange things...
1. i can still allocate 1GB and more
2. a cat cat /proc/user_beancounters shows me failures at privvmpages failcnt=4 - but the script can work and is not killed
3. on the host machine i see in syslog:
Uncharging too much 1 h 0, res unused_privvmpages ub 4
Uncharging too much 1 h 0, res unused_privvmpages ub 4
Uncharging too much 1 h 0, res unused_privvmpages ub 4
Uncharging too much 1 h 0, res unused_privvmpages ub 4
Uncharging too much 1 h 0, res unused_privvmpages ub 4
Uncharging too much 1 h 0, res unused_privvmpages ub 4
Uncharging too much 1 h 0, res unused_privvmpages ub 4
Uncharging too much 1 h 0, res unused_privvmpages ub 4
Uncharging too much 1 h 0, res unused_privvmpages ub 4
Fatal resource shortage: kmemsize, UB 4.
Uncharging too much 65610 h 54827, res unused_privvmpages ub 4
Uncharging too much 3 h 0, res unused_privvmpages ub 4
What does that mean?
4. if i set kmemsize to 655360 the script can only allocate 128MB
Any idea?
