Symptoms
Consider the following scenario:
-
You deploy a very large number of schemas that have the same message type. (That is, the same namespace and root node name.)
-
You turn on message property tracking on the port that processes these messages.
When you send a message of this message type through the port, the BizTalk host instance stops responding. Additionally, the following errors are logged in the event log:
-
