Emby Problems with Version 4.9.1.90

[Buckaroo 6]

I'm having this issue as well, and it seems to be getting worse recently.

Running the official Docker in Unraid. Logs attached.

Emby clients (I've only seen Android, but others on my server have reported similar issues with browsers) will sometimes show a blank screen/refuse to connect if closed and restarted. Restarting the Docker image fixes it for some period of time 9can be days or just hours) but issue always returns. Started noticing this late last year.

Also, apologies. I thought I was replying to this thread, hence the lack of any detail in my first post. Honestly, not sure why that didn't happen.

Anyone had luck on this? I'm still having these hangs every few days. I accidentally started this thread on it. On 4.9.3.0 currently.

Are you still having an issue with this?

Can see some requests to the server that are taking 2 - 2.5 minutes to complete - requests that would normally complete within few milliseconds - these were between 01:06 am and 01:12 am

Are the database files on local storage? - the "/config/data" path

If problems persist may need to enable debug logging on the emby server and provide all logs from launch time to the time when the issue arises and indication as to when this arose / time and date + screenshot to show what was being displayed.

Observation: There are over 18,000 errors/exceptions logged between 00:00 and 01:05 am peaking at over 500 errors a minute and 17 a second. These would impact the performance of the server. It appears that you had media with Anime plugin metadata but then you removed the Anime plugin - is that correct?

Examples of ones from the 18,852 errors in the log

Yes, and all of my Docker appdata sits on a dedicated NVME drive that's not a part of the media array,

Thats interesting - are there steps I could take to mitigate this? Re-add the Anime plugin?

You could try re-adding and then removing it, yes.

I have not tried the sequence of adding Anime plugin, selecting it for library metadata source, removing the plugin

It could be that to remove the Anime plugin, one needs first to remove Anime as being a metadata source in all the relevant library settings, do a refresh metadata with replace all, and then on completion, remove the Anime plugin.

I will try and do a test to see if removing the plugin removes references to Anime metadata or not

Update: It was both plugins: Anime and AniList configured as metadata sources in libraries

@BuckarooI did not get any errors like in your logs after adding the two anime plugins, selecting them in all metadata settings for libraries where they showed as options, refreshing all metadata with replace all selected, and then going through uninstall for each of the 2 plugins

Do you recall what you did? Did you go through Uninstall for each of the plugins?
