Well, looks like you have then multiple clients connecting to this
Zookeeper instance. The documentation says:
maxClientCnxns
(No Java system property)
Limits the number of concurrent connections (at the socket level)
that *a single client, identified by IP address*, may make to a
single member of the ZooKeeper ensemble. This is used to prevent
certain classes of DoS attacks, including file descriptor
exhaustion. The default is 60. Setting this to 0 entirely removes
the limit on concurrent connections.
So, for a single client (IP address), 1024 would be the maximum. If you
have several clients connecting, the actual value could be a multiple
(1024 times the number of unique IP addresses). You may want to check in
the netstat -an what the IP addresses of the clients are and count them
by client.
