Subject Re: how do i have more connections than maxClientCnxns?
Date Thu, 06 Nov 2014 19:46:25 GMT
 echo mntr |nc zk-server-number1-champion-server-of-servering-1.mydomain.net
2181 |grep num_alive
zk_num_alive_connections        1540

And again to verify the setting:
 grep maxClien /etc/zookeeper/zoo.cfg
maxClientCnxns=1024
