[ceph-users] Ceph MDS stuck in reconnect -> rejoin -> failover loop

Hi Ceph pacific 16.2.15 I have 5 MDS hosts, 4 active (4 FS), and 1 standby. One MDS was restarted today (as part of OS Patching), resulting in a failover. This is usually not an issue but today,it got stuck in a reconnect -> rejoin -> failover loop for the specific FS. A ceph fs status shows that during the time the FS is in state "rejoin" the INOS rise to +50M (usually it is around 10-12M ) The memory on the MDS host is eaten, (MDS cache size is 36GB, but it rises to +140 GB.) Finaly it fails over, and the cycle starts over. We are currently restarting all clients, in an effort to rule out buggy clients. Any help on this issue will be very much appreciated. Thank you
