User with no existing session is getting a "Concurrent connection limit reached" error

I have a Citrix Farm 6.5, Windows 2008 with 3 xenapp servers, a web server and a license server.  Within the past week, I have one user out of 70 who continues to get the message Concurrent connection limit reached on all three of the xenapp servers and the user is not logged into either server.  Is there anyway, I can remedy this problem without totally bringing down my servers since this is a medical facility that works all the time and cannot afford the downtime.

Thanks

Yes, the limits are fine.  This is only happening to one user, who is not showing currently that she is logged on at all.  This hotfix was not listed in Citrix AppCenter hotfix summary, so I did not run this.

See this forum, similar to your issue and look at the last response from a Citrix tech support team. That should help:

If I recall correctly I remember once I have seen that a user processes still existed on a server despite the fact that when I checked the users connected to the server the username was not showing.

On the task manager on the server -> go to the processes tab -> From the view menu click 'Select Columns' -> add the 'Session ID' field -> then sort the processes tab with the session ID -> locate the blank ones where, I believe, if these are terminated you will resolve your issue.

basraj - Can you tell me where I can find the queryds tool?

I ran the query tool and saw the user that is having the issue.  Her session id is listed as f.  But I am unable to find it on the server in the task manager.

Sounds like that user has a stuck session.

Go to Admin Tools-->RDS-->RD Manager.  You may find the stuck session there.  Just right click and delete.

Try to recreate lhc once using this command:
dsmaint recreatelhc

If still the same issue, please reboot the server in question (so it kills the unknown process).
