Jellyfin 10.11.1 CPU Spikes when running job 'Jellyfin Recently Added Scan'

[shyamdhokia1]

Description

This job results in massive CPU spikes and I cannot identify clear error or warning logs in either application to indicate the cause.

I have posted this as a Jellyseerr issue as this is likely a result of Jellyseerr not being updated for the new database migration to EFCore on the Jellyfin side. I see no other CPU spikes from Jellyfin.

Jellyseer logs are completely normal, just show the job running and debug logs for every entry in the list being scanned.

Version

2.7.3

Steps to Reproduce

1. Manually run job 'Jellyfin Recently Added Scan'
2. Monitor CPU usage for Jellyfin

Screenshots

No response

These logs from Jellyfin debug may direct to the cause:

There is nothing on our side that needs to be done with the efcore migrations. We dont access jellyfin db directly. We only use their provided api endpoint.

This is not a bug from jellyseerr side. You could try and see if at the moment you trigger jellyfin recently added scan whether the cpu spikes immediately or not. Can you confirm this and report back? And for the time being if it becomes a problem for you, you can increase the cron timings.

I will also confirm whether this is an issue or not on 10.11.0. But once again, we just use api endpoint that jellyfin provides. There's nothing we have to do about efcore migrations.

[fallenbagel]

I just had a conversation about this with the jellyfin dev, @JPVenson and I quote:

Not related to seerr and to the JF spiking CPU usage ... well yes? its doing things that takes CPU.

Therefore, I will be closing this issue

I'm facing the exact same issue, it wasn't happening with Jellyfin 10.10.7 and previouses versions.

These are my spikes:

[shyamdhokia123-ui]

That is very fair, thank you for addressing. It does make sense as EFcore migration is simply adding an ORM and calling API is not changed. I do find the jellyfin devs response perplexing. The request to scan Recently Added is causing disproportionate CPU usage, over 100% on decently powerful HW. This points at an underlying inefficiency/bug in jellyfin backend that is only present since 10.11.0, and specific to this endpoint as no other requests cause this.

[RunAway189]

I downgraded to 10.10.7 since I was having too many issues with the Jellyfin latest version and as you can see, now Jellyfin is not even in the graph. You might be right, the backend is worse right now.

@fallenbagel I did some digging and found that Seerr is making excessive API calls to Jellyfin if you have Sonarr 4k enabled. The PR linked above drastically reduces the number of API calls whilst keeping existing functionality.

This hasn't changed in Seerr any time recently and I'm not familiar with Jellyfin's recent changes. I can only assume their previous versions handled the excessive calls better than now.

Yeah probably. Our jellyfin scanner isn't that robust to be fair. And it was probably handled better on jellyfin side previously (10.11.x brought about a lot of changes unifying the database and using efcore framework).

I will re-open this issue then until the linked pr is reviewed and merged.
