Hello community!
I have a problem on one of my Proxmox hosts. The NIC to which my main network bridge is connected goes DOWN and UP again every few seconds.
The communication between the VMs is not interrupted. Only the communication between VMs and the “outside world”.
The problem does not occur constantly, but every few days. Even a restart did not always solve the problem.
To be honest, I don't know exactly how I fixed the error the last few times ...
At first, I thought it was a hardware problem. Then I put the bridge on the other 10G NIC. After a short time, the error occurred there too.
Now I have temporarily placed the bridge on one of the 1G NICs. For the time being, everything is working again, although more slowly of course.
Here are some brief details about the host:
It is a server ordered in this way with the following components:
- Mainboard H12DSi-NT6 with 2x10G Broadcom BCM57416 (these NICs are the ones affected by the error)
- 1x BCM95719A1904AC PCIe 4x 1G NICs (these work for the time being)
I don't think the rest of the data is important. I can provide it if needed.
This is a short section of the dmesg output:
This is my /etc/network/interfaces:
eno1np0 and eno2np1 are the 10G NICs that make problems.
This is the current configuration with the 1G NICs that works.
I'm at my wit's end.
Does anyone have any ideas on how I can find and solve the problem?
Many, many thanks
Andreas
