This sounds like something has changed with the executable you are using, or
with the computer environment you are running on. If I read this correctly,
you cannot reproduce runs that you made earlier (i.e. starting from the same
input files). You might try recompiling the codes; also, you didn't mention
whether you have run the parallel test cases since this problem surfaced, but
you should do that if you haven't already done so. It could be a bug in
Amber, but this smells more like a problem of file corruption or changes in
the underlying OS or hardware, such that jobs that used to run no longer work.
...good luck...dac
