> Key: CAMEL-6591
> URL: https://issues.apache.org/jira/browse/CAMEL-6591
> Project: Camel
> Issue Type: Bug
> Components: camel-ftp

> 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:
