So from my earlier post on this to give a bit more info.
Our issue is a tiny bit different but the same. We have users that get stuck logging off of our Citrix environment.
They have 4 / 5 hung processes that are all Microsoft stuff. The issue got a tiny bit better with the latest versions of FSLogix as the user at least gets logged off a bit more where Citrix doesn't see the session but its still there with no user attached to it. Sometimes they have the VHD attached sometimes they don't which is nice.
Our session timeouts are pretty long like 8 hours before it logs off users. I am going to try a few changes to log off timers and a few other things.
We aren't sure if its a load thing or maybe a session timeout issue where if users are inactive for so long and stay disconnected is that when FSLogix runs into issues since we barely see this in our test environment and also our smaller delivery groups with less users.
We also use the NetApp in azure we may try swapping some profiles to blog storage to see if that helps as well.
Anyone else somewhat able to figure out the hung session issue or have other things to try?
