What did I do wrong, ZimaBoard running OS onboard 16gb, died while on VPN

[SideOfRanch]

Well I wrote a long post and somehow lost it on submission. While I was on vacation I was able to use the wizard to get the VPN working. It seemed to all be going decent and then all the sudden I noticed viscosity kept disconnecting and reconnecting.

I didn't think much of it and thought it was actually a Wi-Fi issue with the house I was in and not the actual VPN. But then while connected all the sudden my entire router went down and it took down the entire internet of my house. There was nothing I could do to bring it back up I had no way in or out until I returned home 3 days later.

So I just got home took a look at the logs and I'm assuming I can figure something wrong somewhere and caused some sort of crash.

So 2 questions:
1. I took these screenshots of what seems to be the most prevalent errors. https://imgur.com/a/fHL1EXr any idea what I did to cause this?
2. I have it loaded on a ZimaBoard using the onboard 16gb of storage and the dashboard is showing only 2gb of storage remaining. Can I do something to purge logs or something the keep it from running out of space? Could this be contributing to the issue?

I have heard some others on the form having issues with the NIC disconnecting occasionally, and that sounds like what may be happening with your system. OPNsense and other systems built on the same base have issues with NICs that are not intel based from what I can tell. A cheap-ish troubleshooting suggestion would be to get a second hand PCIE intel network card and see if that does away with the problem.
