[Pacemaker] [Problem] The timer which does not stop is discarded.

Hi All,

The timer which is not stopped at the time of the stop of the monitor of the master slave resource of the local node runs.
Therefore, warning to cancel outputs a timer when crmd handles the transition that is in a new state.

I confirm it in the next procedure.

Step1) Constitute a cluster.

Step2) Cause trouble.
[root at srv01 ~]# rm -rf /var/run/resource-agents/Dummy-vip-master.state 

Step3) Warning is displayed by log.

The time-out monitoring with the timer thinks like an unnecessary at the time of the stop of the monitor of the master slave resource of the local node.
