If you can't debug it with an LED or two...haha... Actually I have sometimes used a scope and once or twice have been forced to use a logic analyzer.
You should be able to flash the LED exactly as fast as you can execute a while-loop with a toggle in it. There may be a buffer failure. Are you freeing each message buffer as soon as you are done? Is it the sending or receiving side that dies, and how do we know? My speed tests using T1 and mica's of various flavors were able to run fairly fast for-mostly-ever, although 33/second is about the mica2 limit. What platform are you using?
