Service broker: internal activation on two instances through TRANSPORT route - sql-server

Question

There are servers A and B with the SQL Server instances. There are created services with a route through TRANSPORT. Messages are successfully received. I'm trying to create an internal activation on B, but the queue stops. What am I doing wrong? Fixed. For each message sent from A to B is returned 5 copies.

I'm trying to create an internal activation on B, but the queue stops
That's most likely poison message detection kicking in. It means your activated procedure is raising an exception and cause a rollback. When this happens the output of the procedure (including error messages) is logged into the ERRORLOG. That's where you need to look.
You can also attempt to troubleshoot the procedure by disabling activation and invoking the procedure manually from a query window. This way you'll see directly any error messages/exceptions. To execute under the same context as the activated procedure, issue an EXECUTE AS USER = 'dbo' before invoking the procedure.
See Troubleshooting Activation Stored Procedures.
