Subject: AMBER: Amber9 fails test.parallel

I have built mpich2 with Intel ifort v 9.0 on an em64t
cluster of smp nodes, then built Amber 9 with same compiler
and mpich2. The serial version seems to pass most if not all
the test.serial, however, the parallel tests proceed for a while
then fail with the following error after

cd $AMBERHOME/test
setenv DO_PARALLEL 'mpirun -np 2 ' also tried mpiexec -n 2
mpd &
make test.parallel

Any help or pointers greatly appreciated.
