We started experiencing this TN3270 disconnect issue in early November. It is only effecting folks who connect to our mainframe TN3270 servers from "outside" & it is typically after five minutes of inactivity. Internal users are not seeing the problem & can remain idle for ages. It does not matter which application they connect to. The "network" connectivity remains active, their TN3270 emulator shows a disconnect so they just issue a "connect" again from the emulator. No useful IST messages. Packet trace just shows disconnect ! Firewall folks say everything is okay. We are just living with it. Our TN3270 servers are z/OS 1.9. Regards,
