Is there some reason that you couldn't leave it running once you get the crash? If so, perhaps you could describe those reasons, and I could try helping you overcome them. Being able to look around in a crashed session is important for making the debugging as efficient as possible, given the sporadic nature of the crashes.

Well, if you find some reproducible recipe, it will be appreciated.
