Upvote this problem. We are using the same version 0.8.2.0 and see a
similar issue.
The stacktrace we have seen is
[2015-09-18 08:57:47,147] ERROR [Replica Manager on Broker 58]: Error when
processing fetch request for partition [topic1,22] offset 19068459 from
follower with correlation id 234437
This has happened again on the same system. Is anyone able to offer any
pointers towards a possible cause, as we have no idea what is wrong or how to
stop it happening again.
We need to diagnose and fix this issue soon, as we can't have a live system
that randomly fails due to unknown causes!
