Re: Unusual exception
Hi Avinash, Not sure if you got a response for your email. The exception that you mention mostly means that the client already closed the socket or shutdown. Looks like a client is trying to connect but disconnects before the server can respond. Do you have any such clients? Is this causing any issues with your zookeeper set up?

Re: Unusual exception
EOS means that the client closed the connection (from the point of view of the server). The server then tries to cleanup by closing the socket explicitly, in some cases that results in debug messages you see subsequent. EndOfStreamException: Unable to read additional data from client sessionid 0x0, likely client has closed socket Notice that the session id is 0 - so either this is a zk client that failed before establishing a session, or more likely it's a monitoring/4letterword command (which never est sessions).
