We are currently running a hybrid Citrix environment consisting of XenApp 6.5 ( 80 servers; Windows 2008 R2 ) & XenApp 7.12 ( 60 PVS servers; Windows 2012 ) with Storefront 3.9, NetScaler v12 and Dell WYSE thin clients running ThinOS firmware versions 8.3 and 8.4. We are only utilizing Citrix for application virtualization ( not VDI ).
We are seeing mass Citrix disconnects daily on the thin clients approximately the same time BUT not always the same thin clients. I do not believe this to be a Dell issue but I have checked my timeouts in Storefront & server ICA connections and haven't found anything that would result in this behavior.
Can someone point me in the correct direction or is/has also experienced this issue?
Forgot to mention, the thin clients are only displaying a tracking board with no human interaction what-so-ever ( possibly idle sessions ).
Thank you much.
