Environment

Release : 10.4

Component : CA Service Virtualization

Resolution

Service API call "DELETE /vses/{vseId}/recorders/{recorderId}" will stop the recording virtual service. But, it will not delete the service from portal. 

If you want to remove the stopped service, login to portal and choose "Remove from VSE" option after right click on service name.
If you submit the transaction multiple times, you will get an error message which you have shared.
And the "NullPointerException" reported in case description is a warning message and it can be ignored.
