Xavier Development Kit J202 unstable ethernet connection

We are facing an issue regarding network of our Nvidia Jetson Xavier NX. It seems like ethernet port of carrier board randomly goes down. We need to unplug/plug the ethernet cable to reconnect. It might be a physical issue but I wondered if anyone else having the same problem. Having a hard time to debug since I cannot reproduce it as I desired.

It might be related with this issue fyi: Jetson Mate network issues
