[Pacemaker] Exiting corosync-notifyd results in shutting down of pacemakerd

[Grüninger, Andreas (LGL Extern)]

I am currently investigating the monitoring of corosync/pacemaker with snmp.
crm_mon used with the OCF resource ClusterMon works as it should.

But corosync-notifyd can't be used in our case.
I start corosync-notifyd in the foreground as follows
corosync-notifyd -f -l -s  -m 10.50.235.1

When I stop the running corosync-notifyd with CTRL-C, pacemaker shuts down with the following entries in the logfile.
Is this an error or the desired result?
