Thank you for an advice.

Unfortunately I can't change input data rate (from external source). We are working on slow down input rate. Using debugger cause execution slowdown an we can't deal with current data rate.

Anatoly.

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.
