"Taking too long" is unlikely. Running through the shutdown init
scripts is normally a serial operation, not a parallel one.

It could be that your shutdown script is simply incomplete, and fails
to *finish* stopping a process before proceeding to the next one. If
you wait on each threed to stop, surveying it for status and killing
it whan an ax only if necessary, then you may have a better fighting
chance of getting it shut down gracefully.

I've had some recent work with init scripts that weren't written as
init scripts, that get confused and hang ridiculously awaiting further
input. Issuing yet another "shutdown" or "reboot" command at that
point will simply re-run your shutdown procedures, especially this
shutdown script: that way can lie madness if your "threads" aren't
shut down gracefully.

It sounds like you need more thorough logging of what your shutdown
script does.....
