"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Ok, this means you got some nice problems going on. Your BlackBerry server spawns a "Messaging Agent" which handles your users. The BB Controller service will restart this agent 10 times per day if it fails... once it hits the 10th time it stops bothering, as clearly the issue isnt going to resolve anytime soon.

Back up in your logs and let see if we can figure out WHY the Messaging agent is dieing. If you can, attach your MAGT logs.
This is going to sound too simple... but stopping and starting the Blackberry services in the proper order fixed that same error for me.  Start and stop the BlackBerry services in the following order:
- BlackBerry Router.
- BlackBerry Dispatcher.
- BlackBerry Controller.
- All remaining BlackBerry services.
Good luck.
