Shepherd has been crashing our system with the message:

https://upload.magicbroccoli.de/fb6e7843fef693538a5c7c156c0a98fc0aeb6bac/KmA7ovtC2Fcw0Nm0PSCtphwSyDLI1VUF3QrT9PtD/Kuvakaappaus_-_2025-03-26_13-27-11.png


This ends up with prosody and openssh crashing, nginx still working. the 
picture shows shepherd system-log crashing with:

uncaught exception, value out of range in fibers. It references an 
"unknown file" and a string with prosody.


I looked into git commits in the last month (bug didn't exist before end 
of January/beginning of February, it seems that the bug is either 
shepherd itself, it was updated recently and that is what i was told in 
the irc. Or it is the certbot timer. Certbot timer is the only service 
we have installed from the ones that changed.


Being certbot makes less sense since prosody is mentioned specifically 
tho so it seems a bug in how shepherd parses logs.


Our whole config is here -> https://codeberg.org/joinjabber/Infra
