Hello,
Three OSD daemons crash at the same time while processing the same
object located in an rbd ec4+2 pool leaving a placement group in
inactive down state. Soon after I start the osd daemons back up they
crash again choking on the same object.

Please take a look at the attached log file.
Ceph status reports:
Reduced data availability: 1 pg inactive, 1 pg down
Any hints on how to get this placement group back online would be
greatly appreciated.
