*Hi List,*
*
*
*I'm using ZooKeeper 3.4.3 with jdk 1.6 on a RHEL 5.5 box. On one of the
nodes I constantly get the following warning logs:*

2013-01-04 16:42:15,458 [myid:1] - WARN
 [RecvWorker:2:QuorumCnxManager$RecvWorker@762] - Connection broken for id

 [SendWorker:2:QuorumCnxManager$SendWorker@688] - Send worker leaving thread

*And the corresponding log on node id 2 is:*

2013-01-04 16:42:15,063 [myid:2] - INFO
 [WorkerReceiver[myid=2]:FastLeaderElection@542] - Notification: 2

(n.sid), 0x7 (n.peerEPoch), FOLLOWING (my state)

*These two nodes are both in follower mode.*
*
*
*Besides I also constantly get the following exception:*

2013-01-04 16:46:34,439 [myid:1] - WARN  [NIOServerCxn.Factory:
0.0.0.0/0.0.0.0:2181:NIOServerCnxn@349] - caught end of stream exception

*I try to trace the sessionid, it seems that all the sessions are from the
applications running on id 1 box (We do not use dedicated server for
zookeeper clusters.)*
*
*
*Any ideas?*
*
*
*Thanks.*
