Re: Delta-syncrepl and latency

It looks like the consumer didn't detect that its previous connection

Here is what I found out:
When the idle connection (no write on the provider) reaches the FW TCP
idle timeout threshold, the FW sends out an RST rather than a FIN to
close the connection. That is the reason why the consumer doesn't know
about the connection loss and doesn't try to reconnect right after,
resulting a in a latency.
I may have to use syncrepl in RefreshOnly mode or to make sure that
the connection doesn't get idle for too long.
Thanks for the pointers.
