Unfortunatly, if you've got a stripped binary the output will be totally unreadable. But we can hope. strace tells you the system calls it's doing. If it's stuck in a loop in userspace this won't print much useful, but that fact is useful in itself. Finally there is ltrace which lists library calls. Somewhat more invasive, but can sometimes produce something where strace doesn't. There are tables for the current locks, but you'll need to look in the docs for that.
