This message is issued while processing a DELETE SUBSCRIPTION command with DISCARDOBJECTS=YES. The indicated server cannot be discarded on the managed server because server name is in use. This could occur if the managed server has an active connection to server name or if the managed server has a device class with DEVTYPE=SERVER that refers to server name.
Server server name is not deleted.
Before server name can be deleted, the managed server must not have a connection to that server and the managed server cannot have any device-class references to that server.
