You can try to run your program under strace in order to get more info about what went wrong. Look at the end of the trace to have an idea.

OK, here is a strange one: I have 4 client machines (3 absolutely identical hardware) all running ccp4i from a central server and 2 of the 4 machines (always the same 2) will fail when running a certain scala job with a "child killed" error. I can run the same job on the 2 "good" machines. All the machines call the same ccp4 source file in .tcshrc. I'm stumped. It's probably some sort of cryptic permissions error or something like that. Anyone seen anything like this and have some clue as to the origin of the crash? AFAIK, it only happens running scala in 6.3.0. The home directories for users are served via NFS, but that should be the same for all machines.
