If you need to stop the creation of an AppDisk that has stalled or appears hung up you can run the PowerShell commands to stop and remove the task.
I ran into an issue where the AppDisk test I was creating for Adobe Acrobat XI hung for several hours. I figured that it would eventually timeout after an hour or so and then I could just delete it and start over. I’m not sure if there is a timeout period or not, but after 5+ hours I had to use powershell to stop and remove the AppDisk task.
Load the Citrix PowerShell modules.
get-applibtask -active $true
This command finds all active tasks. I had 2 different AppDisk tasks running. One of my AppDisks task was working correctly, but the last task had been running for several hours.
After running the last PowerShell command. You should see the AppDisk is removed from the console.
