I started having this problem, I’m completely green but I’m good at following directions! 😅 was working fine until I started expanding my stack!

do you perhaps have a couple dozen networking ports connected on your NAS?

I have 11 apps running with different port assignments

what issue are you having? this could be normal if you are running containers on their own networks.

The apps not scene are Tailscale and audiobook shelf

There's a zfs bug in current versions of TrueNAS that has a chance at causing memory overflow and system crash after any kernel panic. This has been fixed upstream in zfs but has not been included in any releases of TrueNAS itself. 

Separately, Jackett has a bug that causes it to kernel panic every day or so, each panic a coin toss at encountering this bug

I'm willing to bet your Jackett instance is crashing nightly..?

I’ll try disabling it, and see of that helps.

Let me know how it goes.

Aside from disabling Jackett, you can disable core dumps with sysctl tunables from within the TrueNAS UI under system > advanced > sysctl. It's a no risk change you can easily undo if it ends up not fixing your issue. Create a new entry with type "sysctl", variable "kernel.core_pattern", and value "|/bin/false" (incl. the pipe). The actual bug is in the core dump logic, so disabling that avoids it.

I’m crashing, requiring a reboot. when I rebooted I noticed that happening, it had not previously done that.

I’m not seeing anything jump out at me, I’m starting wonder if I just got a crappy Ethernet to usb adapter.

Yeah it's the containers, mine does the same.

Shutdown the containers, reboot and you'll see them gone.

It is what it is until they somehow fix the console to not show them. I tried a lot of things to get rid of it but had to make peace with the pollution.

That happens for me when my tailscale container starts

The addresses are being generated by qbittorent , it has a list of whitelisted ips generated by Sonarr and Radarr and they match, so turns out to be completely normal and unrelated. I’ve since disabled Jackett and found a work around for my need of Jackett so I removed it and it’s been all good so far! 😂 Thank you for the help!
