Users are experiencing issues in production environment while trying to login. They are seeing a pop-up 'Application Virtualization Error'. Please advise what are the possible causes for the issue? Could this be an application server related problem?
Detail error message in pop-up: The System is too busy to complete the request. If the problem persists, please report it to your System Administrator
This issue is intermittent and not happening for all the users. I have attached the error screenshot.
