Hi,

We have two routes, incoming and outgoing, that download and upload files to 
SFTP server. Unfortunately, the SFTP server allows just one connection. We have 
tried various solutions and settled on something, that seems to be quite 
complicated - both routes use a timer component followed by shared semaphore. 
Then we use pollEnrich() followed by SFTP endpoint for ingoing files and 
messaging (RMQ) endpoint for outgoing files. Both pollEnrich() run in a loop 
until the there are no more messages to process.

Maybe there is easier way. Maybe we could just have the two independent routes 
and gracefully handle connection errors as expected behavior. But there needs 
to be some limit on error counts, when we cannot connect withing some time or 
number of consecutive errors is high, issue a real connection error.

Thank you for your ideas, Jan
