First, want to justify why I'm positing in this forum before I explain. I've checked all logs elsewhere in my network including my pfSense firewall and cannot find any other location the error pops up except on my main and backup TrueNAS systems. I've tried read the logs in my TrueNAS to see if I could find the unsuppressed version to get more detail, what is splashing on the console is the only information I could find. I've researched this issue, checked TrueNAS forums, looked at FreeBSD forums, can't seem to find much useful information about it. I've compared times that my wife is home and connected to the network and the error doesn't match.
This error pops up every few days randomly, usually there are clusters of the error back to back, there doesn't seem to be a pattern:
I believe it has something to do with hardware that is failing and sending out incorrect MAC addresses across the network (maybe?). I'm trying to understand why this would log on TrueNAS (both production and backup) and no where else. I'm also trying to understand what I can do to locate the source of the error (and throw it out the window).
