That commit should contain the new heartbeat code.

Are the other OSDs also saying that osd.49 is down? Right now it seems 
to me that osd.49 is really down. The "bouncing" I was seeing before 
caused a OSD to mark multiple OSDs down at once, it wouldn't complain 
over and over about the same OSD.

Are you still running XFS with mdraid under the OSDs?
