Description
Task arg has stopped executing. There are too many unhandled error events in the queue. The system can only handle one error event at a time.
Consequences
The system enters a locked state and cannot be restarted until program pointer is moved to any location.
Possible causes
A power outage or controller restart occurred while handling process errors.
Recommended actions
Never restart the controller while handling process errors. If a restart is required, first move PP to Main in all tasks to reset the process error.
