I did see OOME due to KafkaServer resources. 8x 130MB byte arrays caused
the VM to run out of memory. As I said, I can't reproduce it. It's probably not
an issue on master when storm-kafka gets downgraded to 0.8.2.1 (here
https://github.com/apache/storm/pull/1386), since one of the changes in Kafka
0.9.0.1 was to enable the log cleaner thread by default (and thus allocate some
very large byte arrays when starting a server).
