Not sure what to do to fix. Thanks.

mono is at 5.18, 3.10 is really old and will have certificate and tls issues anyway. maybe upgrade that and see what happens? or maybe it really is running out of memory?

3

Yeah, mono 3.10 is too old, you’ll want at least 4.6.

4

I did add 3.6 mono version but sonarr doesn’t seem to be using it… little out of my depth but newer version dose appear for raspberry pi.

5

3.6 or 4.6? 3.6 is older than 3.10 (the zero is significant there, it’s not a standard decimal).

6

It’s definitely not out of memory, top and log confirm.
I tried upedating to mono 5 via
https://www.mono-project.com/
download/stable/#download-lin-raspbian
but afterward version still says
$ mono --version

I tried the same thing with mono 4.6 a while back but sonarr also always only report 3.10.

did you see this page? specifically where you can pick the mono to use as part of the init.d script

its possible the default mono is 3.10 and yours are being installed elsewhere, not upgrading it, and you just have to swap to their location to use them?

8

Thank you for that, that probable would have saved some time :)… I ended up doing a complete removal of all things mono and then reboot and reinstall but that finally seemed to work. Hopefully that will resolve the stability issue. Sadly it broke jacket and sonarr and some other stuff but I think I have everything mostly recovered now :slight_smile:
Kinda scortched earth.
