All the above says is that you tried to run Amber and it failed. Without
*lots* more information, no one would be able to help you.

(As a start, be sure all the test cases run. Next, try a short run with
ntpr=1; does the crash occur right at the beginning or after many steps?
What sort of job is it? what machine/compiler? and so on.)
