If you are getting the “Server is busy” error when uploading a new application, please make sure that these services are up and running on your server:
- PSW Calculation Engine
- PSW Calculation Engine Guard
- PSW Compatibility Engine
- PSW Compatibility Engine Guard
If you have the user rights set up to allow IIS user to start them, you can also do this by going to SystemAdmin > Tools > Administration > Server Status > Click Start next to Engine component. The user that is set up to run IIS worker process (via app pool settings) needs to also have rights to access the services in order to start, stop, or even view them.
