p11_23382: p4_error: interrupt SIGSEGV: 11

Hi,
	I was running a job on 32 processors and it crashed in
the middle with the following message in the .o file (output)

Warning: no access to tty (Bad file descriptor).
Thus no job control in this shell.

There was nothing in the error file. I have run exactly the same program 
but lesser # of grid points, on less # of processors before and it ran 
fine. Since it was running fine before I dont feel that there is a problem 
in the code.

Can there be a problem with MPI?

thanks a lot,
Prateek
