Results:

Client1                         Missed: 203, 253, 293

Client2                         Missed: 204, 252

Client3                         Missed: 247, 252

I don’t know why I am getting packet loss in the Client side. Need some help
as every single notification in our process cannot be missed.
  

You cannot expect one write() on the server side to correspond to one 
messageReceived() call on the client side. The network layer may decide 
to split/combine bytes in order to optimize transport as it sees fit. 
Please have a look at the ProtocolCodecFilter. There's a nice tutorial 
which explains how to use it on the MINA web site. If you are using the 
latest trunk version of MINA I think there is a new codec implmentation 
in there which sends length prefixed string. It seems like you could use 
that out of the box.
