Usually one would investigate something this by running "strace -f -p
<pid>".  If you see syscalls, that's a clue on what it's doing (perhaps
reading files? stuck in some loop?).  Of course I assume you have checked
logs already..

If you are not seeing any syscalls, debugging the process with gdb could
give hints..
