Hello,

Just restarted one of my mons after a month of uptime, memory commit
raised ten times high than before:

13206 root      10 -10 12.8g 8.8g 107m S    65 14.0   0:53.97 ceph-mon

normal one looks like

   30092 root      10 -10 4411m 790m  46m S     1  1.2   1260:28 ceph-mon


Try running 'ceph heap stats', followed by 'ceph heap release', and then
recheck the memory consumption for the monitor.

It had shrinked to 350M RSS over night, so seems I need to restart
this mon again or try with other one to reproduce the problem over
next night. This monitor was a leader so I may check against other
ones and see their peak consumption.

Was that monitor attempting to join the quorum?
