I have also looked through the release notes for 13.0-U3.1 and didn't find anything related to this issue. Has anyone run into this and had any luck resolving it?

I'm running into this. Did you ever figure out what the cause was?

@donschwarz I was never able to resolve this issue. I kept looking for an answer and and the only thing I could come up with is something with my hardware was not playing nice with version 13 of TrueNAS Core. I ended up just spending the money on a Synology becuse I mostly had file storage and the file indexing Synology supports is amazing. That was another piece that was missing from TrueNAS Core. I hope someone can help you and if you figure it out I would love to know what the issues was. Sorry I couldn't be more help.
