I am having a problem with unresponsive threads crashing the server. It
seems that they are not being released even after they exceed the timeout
specified in cf administrator(90 seconds).
It took over 37 minutes for the same template to generate unresponsive
threads. Why doesn't CF drop them when they exceed the time limit?

The template uses a custom tag call that does a cfhttp call to another
template on the same server, trying my hand at a pseudo web service.
Basically:
1. Template calls custom tag for validation.
2. Custom tag calls (local/same cf server) web service url
3. Web service url/template checks if local cache(ms sql db) if user
validation expired. If not expired and validates properly, returns "1".
4. If expired:
Calls a third party web service, which we validate against.
Validation fails, return "0"
Validation succeeds, insert to local db cache, return "1"
I hope that makes sense.
Could that cause problems? I would guess that it would take two threads as
one template calls another... But that shouldn't be to bad.
We've tried tweaking cf administrator a bit, but we're not really sure which
setting to play with.
Thanks for any help.
