However, I don't see any reason for that in a brief look at the OSD log here — can you describe what you did to the OSD during that logging period? (In particular I see a lot of pg_log messages, but not the sub op messages that would be associated with this OSD doing a deep scrub, nor the internal heartbeat timeouts that the other OSDs were generating.) -Greg
