We are running version 3.1.1, and I'm seeing this issue occasionally. I don't know if our dmz is blipping, or if view is actually dropping these connections. We had about 20 users disconnected today at the same time, I saw these errors on all 3 of our security servers.

(B10B75F67E9F3CCC6D640919525F8AB9) No Conveyor for channel 0

(B10B75F67E9F3CCC6D640919525F8AB9) Conveyor 0 IOException. Remote address is null: An existing connection was forcibly closed by the remote host

The KB article said this is supposed to be addressed in 3.1.1?
