Tx Duplex Error

2025-04-07

Hey, another technical question. Earlier today, one of my servers went down. After checking the /var/log/messages log, I discovered some really weird stuff in the log that I have never seen before.

There is about 10x that in the logs.

Anybody recognize what that is? Thanks.
