Re: Unusual exception

2010-10-26 Thread Mahadev Konar 
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?

Thanks
mahadev

Re: Unusual exception

2010-10-20 Thread Patrick Hunt 
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).
