Motivation
This is a fix for #1201.
The truncation happens when, during an unload, the topic moves from one broker to another. If the write operation on the previous connection was still ongoing, it can cause issues when the new IO (associated with the "new" connection) will start writing on the new socket.
Modifications
Take a duplicate of the
ByteBufso that each thread will have its ownreaderIndexon the buffer.
