> 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.
