Proxmox 7 - Losing only SSH connection to node

[gouthamravee]

SOLVED: Am not a smart person. I gave node 4 the same IP as another much older VM and didn't realize because I use FQDNs within my network.

This is a homelab.

After I upgraded all four servers in my pool to 7 I have had a couple of issues.
one is described here -> https://forum.proxmox.com/threads/kernel-panic-whole-server-crashes-about-every-day.91803/

The other is I will randomly lose SSH connectivity with the node, but all the VMs on the node don't lose network connectivity.
I have replaced the ethernet cable with a known good cable, and tried different ports on the switch.
I just caught this happening and the syslog output is below

The corosync logs shows that the network link was down by that time.

The corosync logs shows that the network link was down by that time.

How is it possible for the network link to go down for the host but the VMS running on the host are able to connect?
The host and the VM share the same NIC.

I'm not doing anything exotic with my proxmox setup, they are all running the same version of 7 and are part of a simple cluster.

Did I get that correctly that you run Corosync over the same interface like the WebGUI and the VMs?
Then you most probably already have found your culprit.

Ohh I did not know that was not recommended. I didn't have any issues with 6.x.
Looks like I'm gonna be buying some additional NICs.

I am quite sure that is not possible.

I promise you I'm not crazy, I'm no linux grandmaster but I've been a sys admin for 3+ years now. I wouldn't post on the forums unless I was truly stuck.

I'm not finding anything from system logs, network logs, wireshark, and replacing cables.

So far its just two out of four nodes that are giving me grief. Node 4 was the main one that was dropping SSH before, but last night node 2 started doing the same thing. Where I would lose access to proxmox for a few minutes but all the VMs would be accessible. Node 2 is extra special cause it's hosting my NVR so there's hundreds of megabytes of data going into it per second. Node 2 has 2 NICs one dedicated to the NVR VM, the other is shared by everything else on the node.

Both nodes are also setup to do a quick memtest at boot, I initially thought it was bad ram. I did a full memtest on all the sticks and didn't find bad addresses, I swapped ram around between all 4 nodes so both Node 2 and Node 4 now have 32GB of ram to use, and the boot mem test isn't throwing errors.

I am not opposed to reinstalling proxmox from scratch since I did a 6 -> 7 upgrade. I'll have time to do that over the weekend, but I want to make sure there isn't anything wrong with my configuration that could show up again later.

I am planning on adding a dedicated NIC for the host soon.

I posted the specs for Node 4 above, Node 2 is
