Is WM FtpServer connections multithreaded

We are trying to establish multiple connection using active mode and getting: “Cannot create Dataport 20. Try passive mode” message.

Does anyone know?


Is the first connection succeeding and subsequent connections failing? How are you managing the multiple connections? Out of the box, IS reuses an existing connection within the same IS session that is to the same FTP server. If you don’t like this behavior you have to manage the session yourself OR apply a patch that let’s you force creating a new session.

A firewall may be preventing the connection from being established. Review for information on active vs. passive FTP.
