2. failct=4 and messages like:
Fatal resource shortage: kmemsize, UB 4.
mean that you hit kmemsize limit 4 times.
|
Sorry but failcnt is at privvmpages not at kmemsize (at kmemsize only in my example before...).

3. messages like:
Uncharging too much 1 h 0, res unused_privvmpages ub 4
mean that there is some discrepancy in privvmpages accounting.
This is why I would be happy to your script which reproduces this problem.
|
No problem - you have the small one line script above...
I would be happy if you can help me - if you need anything - write it down - i'll do that.
Thanks!
