> We need to put some sanity checks in QuorumCnxnManager and the other quorum 
> port for rogue clients. Sometimes a clients might get misconfigured and they 
> might send random characters on such ports. We need to make sure that such 
> rogue clients do not bring down the clients and need to put in some sanity 
> checks with respect to packet lengths and deserialization.
