Random Loss of Connectivity (i350)

[SlyFox125]

Hello,

I've attempted to resolve this issue on my own but I've been unable to and am now seeking assistance.

I have a machine running FreeBSD 14.3 utilizing bhyve to host a HomeAssistant instance and a Debian 13 instance running AgentDVR. The instances access my network adapter via a virtual switch. The system randomly loses connectivity - sometimes after mere hours, other times after 2-3 days. I'm unable to access it via the network at all and it never recovers. Upon direct inspection of the system (i.e., at the terminal on the machine itself), I find the nmbd daemon for my samba instance reporting that reload_interfaces has no subnet to listen to. There are no other error messages to be found in dmesg or /var/log/messages. If I attempt the "ifconfig" command, it never loads though the terminal is still responsive. Interrupt (^C) and stop (^Z) have no effect. I must manually power off or restart the machine in order to regain connectivity.

Is there a way to diagnose this further, e.g., am I missing any logs or dump files that I can inspect to figure out what the issue is? Or, of course - better yet - does anyone have a potential solution? The network adapter is an i350; I've already experienced issues with Realtek in the past and transitioned all my machines over to a discrete PCIe card with Intel chips.

What driver? igb(4) or net/intel-em-kmod?

Don't have an issue with mine on igb(4) in my homelab, but I honestly haven't pushed it very hard either.

igb0@pci0:5:0:0:        class=0x020000 rev=0x01 hdr=0x00 vendor=0x8086 device=0x1521 subvendor=0x15d9 subdevice=0x1521
    vendor     = 'Intel Corporation'
    device     = 'I350 Gigabit Network Connection'
    class      = network
    subclass   = ethernet

That said, it was running 15.0-CURRENT and switched to 15.0-STABLE when it became available, never had 14.x on it.

The other notable difference might be, this is a 4 port i310 on the mainboard, not an external card.
