I tried “all” settings. I tried reading the logs and norhing helped. I had many months without issues. How do you guys debug it? The logs aren’t too helpful for me and there are too many settings for me to play with. I’ve got an intel GPU with eirher QSV or VAAPI. Disabling does not work either. CPU is normal, GPU is normal. RAM is not full.

Edit:

• one drive was failing. SMART showed a dying drive. I replaced it and everything is smooth again. That is why I couldn’t find anything within the logs. And until today I didn’t know how to read io properly and check for smart status.

Things to watch out for

• cpu usage
• gpu usage
• right gpu tools. Properly passed to container. Properly used by jellyfin.
• proper transcoding settings with the gpu within jellyfin
• ram
• storage of drives
• io write/read speed
• jellyfin folders on ssd, media on hdd
• healt / smart status of drives
• lan bottleneck
