If they work for a while and then suddenly stop, have you checked the OS
error logs? If there is an error happening, it's going to be recorded
somewhere. It could be something as simple as your app filling up memory
somehow, or having too many open threads to it from the OS' viewpoint.
With exec, if it goes out and executes successfully once, then it's most
likely not broken there, and you might need to go deeper to get to any
kind of issues. Maybe open up the server process list and watch what's
happening while it runs, if you can.
Good luck, chasing this one is going to cost you a bunch of time, sounds
like.
