Connection to sftp server occasionally don't want to come back
--------------------------------------------------------------
Key: CAMEL-4269
URL: https://issues.apache.org/jira/browse/CAMEL-4269
Project: Camel
Issue Type: Bug
Components: camel-ftp
Affects Versions: 2.7.3, 2.7.2
Environment: windows, linux
Reporter: Marek Niewiadomski
Problem appear if somebody kill logged on user on sftp server while you are
connected with consumer.
Camel is not able to reconnect on next poll even if it says that it will do
this.
RemoteFileConsumer is not connected but it thinks that it is still logged in.
I think "loggedIn" flag should be down after each disconnecting action like in
attached patch.
