FIX: Intermittent "no subscribers found" error when you process many messages through a two-way send port in BizTalk Server


View products that this article applies to.

Symptoms

Consider the following scenario:

  • You are using Microsoft BizTalk Server.
  • You have a two-way send port that uses the Windows Communication Foundation (WCF)-based SQL adapter to connect BizTalk applications to an instance of Microsoft SQL Server.
  • The WCF-SQL two-way send port is bound to an orchestration.
  • The send port calls a stored procedure to send messages to the instance of SQL Server.

In this scenario, when you have many messages to process, you may intermittently receive the following error message that states that the process failed and "no subscribers were found":

The Messaging engine failed to process a message submitted by adapter: WCF-Custom Source URL:FilePath.

Details: The published message could not be routed because no subscribers were found. This error occurs if the subscribing orchestration or send port has not been enlisted, or if some of the message properties necessary for subscription evaluation have not been promoted. Please use the Biztalk Administration console to troubleshoot this failure.
