Message processing failed, FTP Receiver Adapter error...

Hello all,

We have a Idoc to File(FTP) scenario using PI.

When PI try to send the file out to the FTP site, we get the following message in the communication channel monitoring and the file never reach the FTP site:

Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error when getting an FTP connection from connection pool: com.sap.aii.af.service.util.concurrent.ResourcePoolException: Unable to create new pooled resource: ConnectException: Connection timed out: connect

When we look at the detail display, we can see that the connection as been establish with the FTP site but the adapter is unable to deliver the file...

Any Idea why?

Thanks in advance.
