Ewen Cheslack-Postava commented on KAFKA-2477:
----------------------------------------------

[~cpsoman] Interesting, the only other org I had heard this affecting was 
seeing it at approximately the same frequency as the original report -- maybe 
once or twice a week. It seemed random, so the events could sometimes clump 
together (e.g. see two in one day), but the average rate was pretty low. It was 
an annoyance rather than a serious issue.

The patch does seem to apply trivially to 0.8.2.2.

> We're seeing some strange behaviour in brokers: a replica will sometimes 
> schedule all segments in a partition for deletion, and then immediately start 
> replicating them back, triggering our check for under-replicating topics.
> This happens on average a couple of times a week, for different brokers and 
> topics.
> We have per-topic retention.ms and retention.bytes configuration, the topics 
> where we've seen this happen are hitting the size limit.
