Resolution

To resolve this issue, clean up the completed provisioning task using PowerShell --

1.) Launch PowerShell
2.) Run asnp Citrix*
3.) Run Get-ProvTask -active $false | Remove-ProvTask (This command will remove entries for all completed tasks from the Machine Creation Service)

Problem Cause

This issue can occur if you have large number of provisioning tasks in the environment.
