This MDS went in and out of replay a few times, but it got stuck on the last one. It looks like it already has the data it needs to proceed, but it's gotten stuck at the wait condition of MDLog::_replay_thread even so. I do see that the last entry it processed is the last one before a log object boundary (and the next event seems to cross that boundary?). And the second object read completed first.
