Okay, WHOA. You are getting a SIGBUS error here. That is caused by either a memory addressing error or reference to an incorrectly aligned address for a datatype - depends on architecture issues for the 2nd. This indicates, most likely, an incorrectly built executable (linked to the wrong stuff perhaps), or perhaps a compiler problem (less likely). Then, looking at your new mdin, you are invoking a generalized Born implicit solvent run (igb = 1), whereas before you were attempting to use pme with explicit solvent under periodic boundary conditions. SO which did you really build - a solvated system for use with pme, or an unsolvated system for use with generalized Born? I would recommend:
1) Test sander.MPI and pmemd by running the test suites that come with amber (read the manual and README's as to how to do this stuff...)
2) Go to the ambermd.org and follow the tutorials link to get to some excellent tutorials written by Ross and others. Play with these for several days, and confirm that they do what they ought to be doing.
3) Then look carefully at how you built your own system and try again.

Hi
I thought we had coz the executable is in one of the amber directories (/opt/brinsoft/amber8/exe/pmemd) on my machine.
So that is what I get
mpirun -np 4 $AMBERHOME/exe/pmemd -O -i minwat.in -o minwat.out -p rldhn_sol.top -c rldhn_sol.crd -r minwat.resrst -ref rldhn_sol.crd

However I also changed my input file to this
# test of minimization
&cntrl
maxcyc=400, imin=1, cut=12.0, igb=1, ntb=0, ntpr=10,
/
And used sanders again, and the minimization seems to be working ok.
But I have to now worry about fixing some residues and letting others move, with the above input.
I appreciate your help
Neville
