[Zookeeper-user] EOFExceptions

[Avinash L. <avi...@gm...>]

I constantly keeping getting this exception on 3 of my servers in the
cluster:

WARN - Trying to connect to a.b.c.d/10.18.39.211:5001
WARN - Priming connection to java.nio.channels.SocketChannel[connected

Is this benign? It wasn't for the last week and suddenly started doing this.

Hi Avinash, you mentioned that this is happening on your 3 servers, 
however this is a client exception afaict from the exception:

ClientCnxn$SendThread.run(ClientCnxn.java:705)

this looks very similar to the following issue which we are currently 
working to address:
https://issues.apache.org/jira/browse/ZOOKEEPER-63
Can you tell is this is printed when the client is closing a session 
with the server?

Patrick

ps. I'd encourage you to move to the new Apache mailing list(s):
http://hadoop.apache.org/zookeeper/mailing_lists.html
