I see floods of this message in my connection server events after upgrading to 6.1.1 from 5.x -- 6.1.1 seems to be significantly more troublesome and less reliable than 5.x -- really wish we could downgrade at this point..
"the pending session on machine xx for user xxx has been expired” . but i then assigned another user to the same desktop, everything looks fine." -- identical symptom on my end
"AGENT_ERR_REQUEST_OVERLAP" -- also see lots of these
"AGENT_ERR_LOGOFF_IN_PROGRESS" -- also see floods of these now, when inspected the machines are already logged off. Allowing a different user to connect usually works without issue.
We have updated the agents on known-good golden templates and the issues occur, and we have tried rebuilding from scratch and the issues still occur. The problem appears to lie with the Agent or Connection Servers themselves. Very frustrating -- our Help Desk is getting hammered with calls from disconnected users trying to reconnect, as well as first-logon users who cannot connect to their floating desktops in the mornings.
