You could try running the master process under gdb. If it terminates abnormally - e.g. something like a segfault - you can then do a backtrace to find out where the problem is happening. Or if you get a "program terminated normally" message, then you know that it's following some code path that causes it to terminate.

I'm not sure about my current failure. I execute my application (MPI processes). Each process executes endless loop. After a couple of hours Master process fails (disappears - I can't see it using 'ps' command). There is no core file. I'm not sure about the reason of failure. It looks strange that single process (15 processes executed) fails w/o core file dropping. I suspect that I'm using MPICH in wrong way, which causes failure. But like I said before I'm not sure about failure.
