Is this the log which you are referring to?

12:04:43 pbxsrv3 pengine: [6396]: notice: unpack_rsc_op: Hard error -
sshd_01_monitor_0 failed with rc=5: Preventing sshd_01 from
re-starting on pbxsrv2


this is normal, because sshd_01 is not supposed to run on pbxsrv2 node, it runs only on pbxsrv1 and pbxsrv3. This error is harmless according to this post http://www.gossamer-threads.com/lists/linuxha/pacemaker/67208#67208

If you read the log on DC, you think that pbx_01, sshd_01 were actually restarted
12:04:43 pbxsrv3 pengine: [6396]: notice: LogActions: Stop resource
pbx_01      (pbxsrv1)
12:04:43 pbxsrv3 pengine: [6396]: notice: LogActions: Stop resource
sshd_01     (pbxsrv1)
12:04:43 pbxsrv3 pengine: [6396]: notice: LogActions: Stop resource
mailAlert_01        (pbxsrv1)

but they weren't.

Cheers,
