I read about mon leak being fixed so I tried to rebuild my cluster from current master (I was badly hit with that leak, as I told on #ceph-devel some time ago) and after a restart of Ceph components, only 29 (out of 98) OSDs were reporting to mons (all of them were running, though), after reverting to the code from around beginning of September, the cluster booted up fine, so either it was a one-time build hiccup, or something nasty went into master recently - I'll check again tomorrow.
