[Beowulf] MPI problem

I'm testing a 12 node Beowulf cluster using torque (an OpenPBS based
program) and mpich with rsh/nfs.

When a submitted a program that generates a big output file at the end
of execution I got this error:

/opt/mpich/bin/mpirun: line 1: 31098 File size limit
exceeded/home/xpto/QCD/su3_ora -p4pg /home/xpto/QCD/PI30888 -
p4wd /home/xpto/QCD

The output file remains with 2.0 GB

Since this error only occurs when I use MPI programs, I suspect this is
some issue related with mpich. Does anyone knows what's the problem?

Thanks for any help
