SYMPTOMS
In Microsoft BizTalk 2004 Server, duplicate messages may appear in the Business Activity Services (BAS) site Inbox and you may receive a warning message that is similar to the following in the event log:

The adapter failed to transmit message going to send port &quot;http:// /StsWebReceive/default.aspx?PartnerId=Partner&FolderType=MessagesInbox&quot;. It will be retransmitted after the retry interval specified for this Send Port. Details: &quot;Unknown Error Description&quot;



CAUSE
This behavior may occur if you send a very large number of messages (600 or more) to a partner.



STATUS
This behavior is by design.



WORKAROUND
To work around this behavior, specify a file name for the message that is sent to the Inbox. You can specify a unique file name in the orchestration for the message that the orchestration sends to the Inbox. Then, if the message is sent two times, the second instance of the message will overwrite the first instance of the message. Therefore, only one message will be in the Inbox.
