Subject [jira] [Created] (CAMEL-6591) SFTP endpoint fails if the server disconnected the socket
Date Tue, 30 Jul 2013 13:15:49 GMT
Stephan Siano created CAMEL-6591:
------------------------------------

             Summary: SFTP endpoint fails if the server disconnected the socket
                 Key: CAMEL-6591
                 URL: https://issues.apache.org/jira/browse/CAMEL-6591
             Project: Camel
          Issue Type: Bug
          Components: camel-ftp
    Affects Versions: 2.11.1
            Reporter: Stephan Siano


If the ssh server disconnects the socket held by an SFTP endpoint (and the disconnect option
is not set to true) the next call to this endpoint will fail. A call after the failed call
will reconnect (and succeed if the server is available again).

The error message is as follows:
