I may have zombies.

I thought I had everything running smoothly, when another group brought
their stuff online. They are connecting through iis (not sure how, will
find out tomorrow as I must now debug the entire project).

My scenario:

typically about 25 users connected through pooled sessions in a 3 tier
environment. Another 5-10 in a pure client server environment, and
another handful through the iis... but these are supposedly connecting,
getting data and shutting down.

I'm finding this isn't the case. In fact, the IIS processes are
consuming an entire processor, and never release ( as if a rogue query
is being run, and the client disappears).

Much more on this tomorrow as i will recreate the problem with some
tools in place to monitor the traffic.

I may revert back to SS, but, seems such a waste, the new server is
screaming fast when things are behaving. Not sure of that has to do
with the quad core, or the new disks and controllers.
