The lsof command is often very useful in this situation.

	lsof -p pid_of_the_hung_process

The strace command may also help, although it probably won't show
much if a process is hung.  It's very useful when attempting to
diagnose problems with program misbehaviour (I recently found
that the SuSE cron process barfed on a CVS directory in one of
the cron.d directories using strace).

	strace -p pid_of_the_hung_process
