Good day!
Surprisingly we encountered ceph-mon core dumped today. It was not peak load time and system was technically in good state.
Configuration
Debian GNU/Linux 6.0 x64
Linux h01 2.6.32-19-pve #1 SMP Wed May 15 07:32:52 CEST 2013 x86_64 GNU/Linux
ii ceph 0.61.3-1~bpo60+1 distributed storage and file system
ii ceph-common 0.61.3-1~bpo60+1 common utilities to mount and interact with a ceph storage cluster
ii ceph-fs-common 0.61.3-1~bpo60+1 common utilities to mount and interact with a ceph file system

ii libcephfs1 0.61.3-1~bpo60+1 Ceph distributed file system client library
Nothing in ceph-mon.log or ceph.log.
Here the back trace if somebody interested.
Core was generated by `/usr/bin/ceph-mon -i 0 --pid-file /var/run/ceph/mon.0.pid -c /etc/ceph/ceph.con'.

Just tell if you need full core its 4,5Gb.
