    Description

      The Initial handshake packet only sends the lowest 32 bits of the thread ID. Taking 4 of the 6 reserved bytes into use for the rest of the thread ID will allow the full thread ID to be sent in the handshake. This removes the need to do a SELECT CONNECTION_ID() to know the real connection ID when the lower 32 bits roll over.

            Since it is only a technicality in the server, and there is no real need to support more that 4 billions concurrent connections at the same time, I'd rather Fix that on the server, than to change protocol to workaround the problem.

            MySQL fixes it in 5.7.5 with https://dev.mysql.com/worklog/task/?id=7293
