ControlSuite has not received a confirmation response from the indicated service within the alotted time frame.
This may not be indicative of a larger issue. Often, this just means that more time is required for the service to complete the stop/start action. In these cases, verify the current status of the service in the Status column of the Services table. As seen below, Pending status indicates that the action is still being processed and likely just needs more time to complete.
