Description

We upgraded our R+D cluster to 1.0 in the hope that it would fix the deadlock from 0.11.0.*. Sadly our cluster has the memory leak issues with 1.0 most likely from https://issues.apache.org/jira/browse/KAFKA-6185. We are running one server on a patched version of 1.0 with the pull request from that.

However today we have had two different servers fall over for non-heap related reasons. The exceptions in the kafka log are :
