Everything That Will Cause A Queue To Shut Down

I have a queue that, after running fine for several days will mysteriously turn off. It doesn't seem to be related to a poison message because I can restart the queue and processing resumes just fine. What are all the scenarios that would cause a queue to turn itself off, so I can 1) take preemptive action to prevent it from happening in the first place and 2) respond appropriately when it occurs.



Also, how to properly setup and verify that the BROKER_QUEUE_DISABLED is working properly. This is the SQL that I have so far, but is there a more direct way to raise the event other than writing an activated stored procedure that rolls back 5 times?



CREATE QUEUE [EventNotificationsQueue];

GO

CREATE SERVICE [EventNotificationsService]

ON QUEUE [EventNotificationsQueue]

([http://schemas.microsoft.com/SQL/Notifications/PostEventNotification]);

GO



CREATE EVENT NOTIFICATION [QueueDisabled]

ON QUEUE [MyQueue]

FOR BROKER_QUEUE_DISABLED

TO SERVICE 'EventNotificationsService', 'MyDatabase';

GO
