Hello fellow Cephers!
Recently, before and after the update from 0.77 to 0.78, about half the OSDs in my cluster crash quite frequently with 'osd/PG.cc: 5255: FAILED assert(0 == "we got a bad state machine event")'I'm not sure if this is a bug (there are some similar-sounding reports in Redmine already), or a configuration/corruption issue on my cluster.
I've got 22 OSDs on 5 hosts, running 0.78 across the board. Any pointers would be appreciated! I'd like to track down and resolve the issue, it's causing a lot of stalled requests from clients and seems like a generally-unhealthy state of being.

Here's a fresh log file (~3MiB) from one OSD that crashed (old log moved aside before restarting after crash):
