Ben Corlett created KAFKA-6194:
----------------------------------

             Summary: Server crash
                 Key: KAFKA-6194
                 URL: https://issues.apache.org/jira/browse/KAFKA-6194
             Project: Kafka
          Issue Type: Bug
          Components: core
    Affects Versions: 1.0.0
         Environment: kafka version: 1.0
client versions: 0.8.2.1-0.10.2.1
platform: aws (eu-west-1a)
nodes: 36 x r4.xlarge
disk storage: 2.5 tb per node (~73% usage per node)
topics: 250
number of partitions: 48k (approx)
os: ubuntu 14.04
jvm: Java(TM) SE Runtime Environment (build 1.8.0_131-b11), Java HotSpot(TM) 64-Bit Server
VM (build 25.131-b11, mixed mode)
            Reporter: Ben Corlett


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 :
