k2U79!KvW9AXpwAc Posted September 3, 2020 Share Posted September 3, 2020 (edited) My Unraid box occasionally disappears from the network. If I leave it alone long enough, it comes back. Looking at the logs, the first sign of a problem seems to be the log entry "kernel: bnx2 0000:01:00.1 eth1: NIC Copper Link is Down". Then there's about 1:20:00 of restarting things before the log calms down. How can I avoid this? I'm running Unraid 6.8.3 on a restored Dell PowerEdge T410. I have a diagnostics dump ready, trying to figure out how to upload it Local processes seem unaffected. Folding@Home appears to keep trucking along in it's Docker. My uptime counter doesn't reset. You'll notice that I've got 6GB total RAM; I have 8GB installed but one of the motherboard's memory channels is dead. There are two network interfaces on the motherboard. They're both wired to the same unmanaged gigabit switch. I initially only had one network interface connected, but set up the second one when this problem first occurred. I was hoping that maybe a redundant network connection would persist through the reset, but apparently not. I have some USB Ethernet adapters around... third interface is the charm?? PS I have run the "Fix Common Problems" app. I tweaked some configs and have no warnings except for "CPU Scaling Driver," which I'm not inclined to dig into at the moment unless there's a reason to think heat problems are causing my network problems. tammy-diagnostics-20200903-1535.zip Edited September 3, 2020 by k2U79!KvW9AXpwAc added info about Common Problems app Quote Link to comment
JorgeB Posted September 4, 2020 Share Posted September 4, 2020 If you have one try with a different NIC, ideally one from Intel. Quote Link to comment
