Hi, when the monitoring is disabled (unmonitor), or monit is stopped then the service's error state is reset. When the monitoring is enabled (or monit started) again and the service is running, no recovery alert is send as the service monitoring starts from clean state.
The unmonitor is performed at the start of the service check - if by coincidence the test of some service is in progress, it allows it to complete the test of that single service and doesn't interrupt the pending check. When monit goes to next service (in the same cycle) it disables the monitoring. I think it's OK to let the pending test complete - it's kind of corner case with low impact.
