I think it's because you have too full osds like in warning message. I had similiar problem recently and i did:
ceph osd reweight-by-utilization2014-10-20 14:45 GMT+02:00 Harald Rößler <Harald.Roessler@xxxxxx>:
Dear All

I have tried to restart all OSD in the cluster, but does not help to finish the recovery of the cluster.
Have someone any idea
Kind Regards
