Thanks for the response!

Apparently, as a neighbour kernel hacker just explained me, this is not a bug.

The problem is tcp time wait buckets are still there after VPS is stopped, thus we are having >0 kmemsize. They should go away after a timeout (5 minutes or so), after that kmemsize will be set (zeroed) and fail counters should be reset to zero.

'oomguarpages > 0' is known bug; the good thing is fail counters will be reset even with oomguarpages > 0.

So, you have two options
(1) stop VPS and wait 5 minutes or so
(2) check the difference of failcnts, not their absolute values.
