Netty-server-localhost-6700-worker-1 [INFO] Received error in netty thread..
terminating server... {code}
It seems related to https://issues.apache.org/jira/browse/STORM-3141 but seems
to have been fixed in 2.0.
I am happy to provide more information but at the moment am unsure of what is
relevant.
I have a suspicion that this is related to load-aware localOrShuffleGrouping
("LoadAwareShuffleGrouping") because this issue seems to have started when I
switched the Grouping, but again, not sure if it's actually related.
