GW 8.0.2HP2 agents on Windows Server 2008 Standard

I have a couple of post offices that show busy C/S Handler Threads on the POA web console Status screen. Here are two examples..

Threads Request count State Time Elapsed (Secs)
GWTCP-GWPO-Handler_26 422727 Handle Request 2277685
GWTCP-GWPO-Handler_12 408632 Handle Request 1125542


2277685 seconds is 632.6902777777777 hours. Access mode is "Online" and Current Transaction is "Login".
1125542 seconds is 312.6505555555555 hours. Access mode is "Online" and Current Transaction is "Verify and authenticate".


Is there a way to close these from the agent/server (i.e. without trying to locate the user and close the client or restarting services/server)?

TIA,
Steve
