Citix ICA Client File intermittently not downloading on app request
Posted on 2012-09-08
We have been having an issue where applications are not loading when selected. Given the time-frame of these occurrences it seems to me that when this happens the system is too busy to serve/create the ICA file that kickstarts the session. Applications seems to have no issue launching in the early morning, but as the demand increases we see failure to launch happening more and more throughout the day. It can take multiple atempts before the file is available.
My admin has added more Citrix servers to the farm in response, but this seems to not help. When an application is chosen what mechanism creates the ICA file? Is it the actual server the app has been load balanced on, or it is some sort of initial gateway/session generator on one device?
It seems to me that it's one device that is simply overwhelmed by the number of connection requests and fails to provide the connection file.
If someone provide provide some insight on the mechanics of a session from request to completion it would be much appreciated.
