Hi, This might be the pglog issue which has been coming up a few times on the list. If the OSD cannot boot without going OOM, you might have success by trimming the pglog, e.g. search this list for "ceph-objectstore-tool --op trim-pg-log" for some recipes. The thread "OSDs taking too much memory, for pglog" in particular might help.
