Does not return in timely manner from Run -- sql server notification services

What can cause this error to occur: "The application did
not return in a timely manner from the Run method." The
terribly unfortunate behavior in these circumstances is
that NS shuts down the custom Event Provider that timed
out. Even more unfortunate is that the process continues
to run, but of course it doesn't do anything because the
Event Provider is not running. What possible alternatives
are there to handle this situation more robustly? I have
all of the code in my Run method in a try/catch block, and
I return true from the catch block. In this case I logged
no exception -- the only error was the Notification
Services-generated error about not returning in a timely
manner. Can a simple database timeout cause this? Or can

This error message is logged when the Run() method does not return within
five minutes.

IEventProvider.Run() is not called within a thread by NS. As such, the Run()
method usually needs to start up its own thread, or fire up some CLR event
handlers.
