FTP receive adapter fails to publish message if receive pipeline processing time exceeds server time-out

Problem

A message received via the FTP adapter is not published to the MessageBox database. You may see errors similar to the following in the Application log for the BizTalk Server computer:

Event Type:Error Event Source:BizTalk Server 2006 Event Category:BizTalk Server 2006 Event ID:5719 Date:6/30/2006 Time:12:08:55 PM User:N/A Computer:BIZTALKSERVER Description: There was a failure executing the receive pipeline: "Microsoft.BizTalk.DefaultPipelines.PassThruReceive, Microsoft.BizTalk.DefaultPipelines, Version=3.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "Pipeline " Receive Port: "ReceivePort1" URI: "ftp://FTPSERVER:21/*.txt" Reason: Unable to receive the file "file.txt " from the FTP server.

and

Event Type:Warning Event Source:BizTalk Server 2006 Event Category:BizTalk Server 2006 Event ID:5740 Date:6/30/2006 Time:12:08:56 PM User:N/A Computer:BIZTALKSERVER Description: The adapter "FTP" raised an error message. Details "Unable to receive the file "file.txt " from the FTP server. ".

Cause

The time taken to complete pipeline processing exceeds the FTP connection time-out.

Resolution

Use one of the following methods to mitigate this problem:

· Increase the connection time-out value. Set the idle time-out value on the FTP server to be at least the amount of the time it takes to process the file.

· Use the Temporary Folder feature on the receive location. In this case, the FTP adapter copies the file to the temporary folder (typically the local disk). It typically takes less time to copy the file to the local disk than to run the message through the pipeline and persist it to the MessageBox database, which effectively reduces the idle time.
