Hello!
I see similar behavior on a build of version 9.2.0-702-g7d926ce
Single node.
Ceph Mon only service that is running.
In Ceph configuration file (/etc/ceph/ceph.conf)
ms_crc_header = false
$ ceph -s
2015-11-13 16:06:24.594453 7f6944221700 0 -- 17.10.10.60:0/1019560 >> 17.10.10.60:6789/0 pipe(0x7f6940020260 sd=3 :55541 s=2 pgs=3 cs=1 l=1 c=0x7f69400204f0).reader got bad header crc 2721288891 != 0
Commenting out the ms_crc_header makes ceph status run.

Restart ceph-mon -i hostname
