And that is absolutely ok when corosync dies. Corosync does not die but is still healthy. It is corosync-notifyd which is started additionally to corosync as a separate process and which is finished with kill as daemon or with ctrl-c as foreground process. The job of corosync-notifyd is sending of SNMP traps. This is the functionality of crm_mon -C .. -S ... for pacemaker. So corosync-notifyd sends the wrong signal or pacemaker does a little bit too much. Pacemaker should just ignore this ending connection. Is there a chance in pacemaker or should should this better solved in corosync/corosync-notifyd?
