>
> The current replica fetcher thread will retry in a tight loop if any error 
> occurs during the fetch call. For example, we've seen cases where the fetch 
> continuously throws a connection refused exception leading to several replica 
> fetcher threads that spin in a pretty tight loop.
> To a much lesser degree this is also an issue in the consumer fetcher thread, 
> although the fact that erroring partitions are removed so a leader can be 
> re-discovered helps some.
