Does it use X?  If so, try setting your DISPLAY to another box.  (Maybe it's
hanging the X server.)  If not, try ssh'ing into the box from another
machine.  Can you run top in another window while it runs?  Perhaps it's
chewing up gobs of memory (got any monster range() calls in there)?

If you give us some more details about how you think it's supposed to
interact with the system we might be able to provide some more debugging
clues.
