FTP Adapter Common Error BizTalk server

You receive a "Failure occurred in parsing the remote folder listing" error message when you try to retrieve documents from or send documents to an FTP server

Problem

When you try to retrieve documents from or send documents to an FTP server by using the Microsoft BizTalk Server  FTP adapter, you receive an error message that is similar to the following:

A failure occurred in parsing the remote folder listing.

Cause

You may receive this error message if the following conditions are true:

• The receive handler or the send handler for the BizTalk Server FTP adapter is configured to use a firewall mode of Passive.
• The target FTP server does not permit passive connections.

Resolution

To resolve this behavior, use one of the following methods:

• Configure the receive handler or the send handler, or both, for the BizTalk Server  FTP adapter to use a firewall mode of Active.
• Configure the target FTP server to permit passive connections.

The FTP adapter can be used to connect to FTP servers on systems ranging from Solaris and Linux to AS/400. For more information about connecting to legacy systems, see Configuring an FTP Adapter to Work with Legacy Hosts.

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. 

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.
