> Looking at the replication for some other reason I noticed that the
> replication source might be a bit too eager to remove sinks from the list of
> valid sinks.
> The current logic allows a sink to fail N times (default 3) and then it will
> be remove from the sinks. But note that this failure count is never reduced,
> so given enough runtime and some network glitches _every_ sink will
> eventually be removed. When all sink are removed the source pick new sinks
> and the counter is set to 0 for all of them.
> I think we should change to reset the counter each time we successfully
> replicate something to the sink (which proves the sink isn't dead). Or we
> could decrease the counter each time we successfully replication, that might
> be better - if we consistently fail more attempts than we succeed the sink
> should be removed.
