 Description   

SXP does not release outbound messages after writing them out to wire => ByteBuf is reference-counted type in Netty and JVM is not aware of the reference counting Netty implements, it will automatically GC them once they become unreachable
even if their reference counts are not zero, and memory leak be created.
