sometimes had same issue on DRBD 9.0.14. Sometimes 
drbdsetup events2 --statistics --now
on both nodes shows different number Out-of-Sync (OOS) blocks (in situation
where OOS number doesn't changes - sync freezed).

I didn't found steps to reproduce this error. It happens randomly.

Temporary solution is 
drbd down drbd0
drbd up drbd0
on node with inconsistent resource

Permanent solution is (I hope) upgrade to DRBD 9.0.15.
