[ClusterLabs] Monitor being called repeatedly for Master/Slave resource despite monitor returning failure

I have configured wildfly resource in master slave mode on a 6 VM cluster
with stonith disabled and and no quorum policy set to ignore.

We are observing that on either of master or slave resource failure,
pacemaker keeps on calling stateful_monitor for wildfly repeatedly, despite
us returning appropriate failure return codes on monitor failure for both
master (failure rc=OCF_MASTER_FAILED) and slave (failure

This continues till failure-timeout is reached after which the resource
gets demoted and stopped in case of master monitor failure, and stopped in
case of slave monitor failure.

Could you please help me understand:
Why don't pacemaker demotes or stops resource immediately after first
failure, and keeps calling monitor ?

Could you please help us in understanding this behavior and how to fix this?
