DHCPv6 service going down periodically (every 2-12 minutes)

[emilk]

Hi there,

I'm having problems with the IPV6 service going down intermittently. (every 2-12 minutes).
I feel like I'm going nuts here, I even reinstalled OPNsense from scratch to see if that would fix anything, but stuck with the same problem. Any suggestions for how to proceed here?

Here's the dmesg output:

Here's my hardware info: https://bsd-hardware.info/?probe=92f9cb26f3

I hope one of you smart people here in the forums can help spot where this is going wrong.
Fingers crossed this isn't a looming hardware failure.

I've tried following the "prevent release" tip found in this other forum thread, but that doesn't fix the problem unfortunately - still getting errors like these that insist that the ipv6 process is first killed, but then afterwards errors about the process already running:

[opnfwb]

Based on the dmesg it looks like igc0 is up/down quite a bit? Is that interface negotiating at the right speed? Maybe worth double checking the cable there just to rule out a physical issue?

[emilk]

Thanks for the quick response @opnfwb!

igc0 is showing up as 1000baseT <full-duplex>:

Swapped out the cable and rebooted now - I'll wait and see if that fixes anything, fingers crossed.

[emilk]

@opnfwb I *think* it's working now! Must have been the cable!
No problems for >15 minutes is definitely a new record.

[emilk]

Several hours later and everything is still running rock solid! Thank you so much @opnfwb, you rock!
