My best guess with those symptoms, if it isn't a hardware problem, is one or more of the affected NICs ending up on the same IRQ as a USB controller or something else that's causing issues. Most of the time that's no big deal, on occasion with certain systems with several NICs it can cause packet loss or performance issues. If that's the case, may find a BIOS update that fixes it, or may be able to muck with BIOS settings to make it go away. > It is possible it is a hardware failure, but I want to see what other > experience is out there. > > When looking at the network interface statistics, there are zero errors. > > > thanks, > > Geoff > > > _______________________________________________ > pfSense mailing list > https://lists.pfsense.org/mailman/listinfo/list > Support the project with Gold! https://pfsense.org/gold _______________________________________________ pfSense mailing list https://lists.pfsense.org/mailman/listinfo/list Support the project with Gold! https://pfsense.org/gold
