Failed to create CoreCLR, HRESULT: 0x80004005

Fresh install, jellyfin-10.8.10_2 (built from source with poudriere), allow.mlock and allow.raw_sockets enabled, no limits:

Failed to create CoreCLR, HRESULT: 0x80004005

I've seen #6 but have a different code.

jellyfin/jellyfin#2616 looks similar, but Unraid is a Linux distro, not FreeBSD.

It might need a writable TMPDIR. You can set this (e.g., setenv, export, whateveryourshelluses)

edit: or you have 0 bytes of free space
edit 2: or even more obscure: W^X issue kern.elf64.allow_wx should be 1
@mord0d give those a try :)

No luck.

or you have 0 bytes of free space

# df -h
Filesystem                    Size    Used   Avail Capacity  Mounted on
serv/jails/media/root         1.2T    632M    1.2T     0%    /

Don't think that it requires tmpfs(5).

or even more obscure: W^X issue kern.elf64.allow_wx should be 1

Oh, that's it! Thank you!

@mord0d That last one is not a great solution as it turns off W^X protections system-wide, which if it was originally 0 means either you or a hardening script put it that way.

elfctl reports:

File 'jellyfin' features:
noaslr          'Disable ASLR' is unset.
noprotmax       'Disable implicit PROT_MAX' is unset.
nostackgap      'Disable stack gap' is unset.
wxneeded        'Requires W+X mappings' is unset.
la48            'amd64: Limit user VA to 48bit' is unset.

If you want: revert the sysctl change. elfctl -e +wxneeded the jellyfin binary and see if it works.

If it DOES work then I need to find out why jellyfin does not work with W^X protection under FreeBSD

[mord0d]

if it was originally 0

Nope, it's 1 by default.

It works.
