I suspect that *very* few people are using PIMD in Amber any more, and
even fewer with the normal mode option. We call all hope that someone
recognizes the problem and can chime in, but you may need to face the
need to explore the origins of this problem yourself.

Look for test cases that are closest to the simulations you wish to do,
and see if they work for you, and whether or not you can carry out a
restart with those systems.
