That's not an MDS crash. The MDS is respawning itself because it got a message from the monitor indicating that it had been removed from the MDSMap. That will happen if the mon and MDS lose contact for too long, which appears to have happened here (lost contact for about 40 seconds up to the time 13:42:20, when the new mdsmap is received). You will need to diagnose what caused the mon and MDS to lose contact during this time window, or possibly what caused the mons to be unresponsive if that was the case.
