Can you close the application when the user disconnects?

I am running a 7 server farm on 4.0 (recently upgraded from 3). I had the same problem with 3 so I was hoping an upgrade to 4 would fix it but it didn't. All servers are Dell dual Xeons with hyperthreading enabled, Windows Server 2003 (non SP1). All clients are either Windows XP or 2000 with version 8.1 of the Citrix client. I am only publishing one application that can serve up to 200 users through the PN agent. Also, I have a few computers that are accessing this through the web interface. Intermittently when a session disconnects, the processor will go to 25% and stay there. I would assume the 25% (and not 50 or 100%) is due to the hyperthreading. Obviously, if 4 sessions are screwed up on the same server, I have a problem. I've set up the session to reset after 65 minutes of disconnected or idle time. However, the disconnected session will not always reset itself because (I would assume) the processor is too busy. I've checked with the vendor of the application and they say that it is a Citrix problem, but the process pegging the CPU is this vendor's application. Does anybody have any ideas on how I can try to troubleshoot this? Thanks in advance. Brian Lich
