This indicates that your mirror maker and/or your zookeeper cluster is
GCing for long periods of time. I have observed that if "client session
timed out" happens too many times, the client tends to lose zookeeper
watches. This is a potential bug in zookeeper. If this happens, your mirror
maker instance might not rebalance correctly and will start losing data.
You mentioned consumption/production stopped on your mirror maker, could
you please take a thread dump and point us to it? Meanwhile, you might want
to fix the GC pauses.
