MPICH uses a few extra flags to pass information to the application.
p4pg tells where the p4 procgroup file (automatically generated by mpirun)
is. Normally AMBER ignores the p4pg flag (see mdfil.f).
I would suggest you check your mdfil.f to make sure it skips p4pg.
Amber-6.0 should skip it, do you have a "test" version of AMBER6 or did
you change the source code in any way?
