IBM x360 server: Ran fine for a year on Redhat AS2.1 on the same subnet it's on now. Re-installed to Redhat AS3.0 and after about a month, the NIC started to go offline once per day or so. At the console, we see:
You can bring the adapter back on-line by removing and re-inserting the ethernet cable, or by bringing the interface down and back up again. Originally running the e100 driver. Changed to eepro100 today as a test. Holding steady using the older eepro100 driver, but saw some "overruns" in ifconfig output.
Before the NIC goes off-line, we see a build up of "overruns" packets listed in "ifconfig eth0" output,such as the following:
RX packets:363057100 errors:0 dropped:0 overruns:452 frame:0
When the NIC goes off-line, that "overruns:" value may be around 12,000 packets.
Note also, that this same problem has happened on 4 servers, all identical hardware and software on the same subnet. Very random, but we've seen all four servers experience the problem at the same time a couple of times.
