Its somewhat inferred in the description of cluster-recheck-interval
cluster-recheck-interval = time [15min]
Polling interval for time based changes to options, resource
parameters and constraints.
The Cluster is primarily event driven, however the configuration can
have elements that change based on time. To ensure these changes take effect,
we can optionally poll the cluster's status for changes. Allowed values: Zero
disables polling. Positive values are an interval in seconds (unless other SI
units are specified.
eg. 5min)
the failure-timeout doesn't result in any events on its own, so the
reprocessing happens the next time the PE gets kicked by the recheck timer.
