    Not sure if this is an issue or not, but if multiple connections (from a new address)
hit this line before reaching the next one, the maxclientcnxns will never be checked as factory.ipMap.get(address)
will return null for all of the connections?

> Even though NettyServerCnxnFactory has maxClientCnxns (default to 60) it doesn't enforce
this limit in the code.
