2) Is this expected behavior for Storm to be unable to keep up with heartbeat
threads under high CPU or is our theory incorrect?
Check your JVM max heap size (-Xmx). If you use too much, the JVM will
garbage-collect, and that will stop everything--including the thread whose job
it is to do t
se to make our topology more
resilient to these restarts?

OK, so GC is probably not the issue.
Specifically, this is a connection timeout to ZK fr
zookeeper 3.4.5 installed. I see Storm uses zookeeper-3.3.3 as its
client. Should we downgrade our installation?
