Atmosphere On message Throwing message multiple times on single push - atmosphere

Question

Hi i am learning Atmosphere framework and new to it, please help me out to fix issue that when i am pushing message through
socket.push(atmosphere.util.stringifyJSON({author:"user1", message: "hello"}));
but on server side i could see ***{"author":"user1","message":"hello"}, 4 times for single push.
