When a client using Advanced Log Transport Protocol (ALTP) connects to the server for the first time, it generates a persistent ID and sends it to the server during the handshake process. This is the TID.
If the client loses the connection to the server silently, for example, the UTP cable is pulled from the host or other network issues happen, the server is unable to detect the connection loss.
If the client tries to reconnect within a short time interval, it will send the same TID. However, the server allows only one connection with the same TID. As the server “thinks” that it already has a live connection with this TID, it drops the new connection due to the duplicated TID.
