this is a zombie process, it's already dead. look for "zombie" in man ps.

Yeah, try "kill -9 processID".

Is there any way (besides rebooting) to kill processes that just don't seem
to want to die?
I don't believe the process has any child threads or processes, but its not
responding to any type of kill signal:

I've had this problem with other UNIX/type OS's before on different
machines, but I never could find out why.
