I have encountered a scenario where the PLC connection appeared to be
disconnected, but in reality it was still connected due to certain reasons.
However, we kept trying to reconnect and as a result, the TCP estab value
increased to tens of thousands. This caused the PLC to be disconnected and also
resulted in server network issues. Therefore, I'm looking to see if there is a
better solution available.
