Has anyone have the session limit reached with - as the user? Citrix does not know why and the only way to resolve it is to reboot.

check the web for ghost sessions, lots of people have had this happen. You can try rebooting the Desktop Service, that sometimes brings it back, but in my testing a reboot is the best option.

Thanks, I google first before asking but nothing in google or restarting the service helped. It seems like the Citrix DaaS Db does not update the db current user and only a reboot resolves the issue. RDP still works.
