ZooKeeper keeps getting EndOfStreamException, causing a crash

I was able to solve the problem by deleting all zookeeper snapshots and log files from the server running ZooKeeper. I don't know why this made a difference, but it has been running fine for the last 22 hours.

**This exception is an indicator of the end of the data stream of a session. It usually occurs when closing a connection to zookeeper. This exception does not signal a defect on the zookeeper side. Instead, it shows a connection to client is reset or closed. So please ignore the warning.
