Hi,
My scenario is File --> IDoc.The source file has to be picked from an FTP server.XI is configured to poll the server every 5 minutes.But frequently the sender channel throws FTP connectivity issue.
"An error occurred while connecting to the FTP server <Servername>. The FTP server returned the following error message: 'com.sap.aii.adapter.file.ftp.FTPEx: 421 Service not available, closing control connection.'. For details, contact your FTP server vendor."
Could someone help on the issue.I have a vague idea about FTP error 421 : FTP server limits the total number of connections available or limits the connections available to one user.
Where do I need to change the limitation?
Regards,
Shanthi.
