So it happened again with the same OSD? Did you see this with other
OSDs?
Try enabling some logging on osd.13 since this seems to be a recurring
issue. At least "debug ms = 1" so we can see whether it ever sends the
reply to the original op (i.e. prior to restart).
Also, take note of the epoch in osdc output:
36 osd13 ... e327 ...
Does "ceph osd dump" show the same epoch when things are stuck?
Thanks,
Ilya
