Endpoint shutdown (FTP) on web exception. FTP error 421

Question

Hi,
When using FTP Source in my Biztalk Services project it sometimes occurs that we receive an error 421 from the FTP server. This causes the endpoint to shutdown, which will result in a manual action to restart the endpoint again.
We're looking into the cause of the 421 error, but the strange thing is that 4 bridges within the same project use the same FTP server, but they do not all shutdown. This makes it assumable that it's a short hickup in the system.
Is there a way to set a strategy of backoff and retrying instead of shutting down the endpoint for FTP errors ? I my opinion, /I shouldn't need to rely on a 3rd party to keep my infrastructure running.

Answer 1

The bridge will shut down after retry attempts at delayed polling intervals.
You may want to monitor Operation Logs / Event logs for such events.
You may write a simple PS script which can run periodically to start the bridges and make sure that the bridges are in started state.
