Running 6.5sp5 (yeah I know, upgrade to sp8).

Had a failed index creation that hung after a couple hours. I tried to
cancel the indexing and it said it was cancelling for a couple of days. Then
I tried to delete the indexing job and now it says "Deleting", but nothing
seems to be happening.

I unloaded tomcat with TC4STOP

I tried to unload QFJW22.NLM. but it won't let me, "Module QuickFinder
Server Native Query Wrapper cannot be unloaded at this time"

Is the only way to stop these indexing jobs going to be downing the server?
