Description Andrej Nemec 2019-01-07 10:21:37 UTC
Monit may crash if "unmonitor" or "stop" action was triggered by some test: the _handleAction() will call Util_monitorUnset() which frees the service events list, including the current event which triggered the action. The reset of the state_change flag (which is not necessary) then dereferenced a freed event.
