Originally I had noticed the errors on the bond interface but if you look,
the error count on the bonded interface is just a total of the errors on
all of the slaves that are part of that bond (3 out of 4 slaves have
overruns). I’m classifying these as overruns simply because that is how
they show up in the output from ifconfig.
RX packets:100971364 errors:142 dropped:0 overruns:142 frame:0
That is a pretty small amount of errors compared to the total but it has
me concerned that they are building on several of our servers. If you’re
saying this is something that doesn’t need to be worried about then I can
live with that but it seems like ideally there should be 0 errors.
Here’s the output you asked for on one of the interfaces building errors:
