Refreshing library stuck at 30.3%. CPU pegged at 99%

[Mark-Ev 0]

Can't seem to update metadata or refresh media library. Synology CPU pegs at 99% and stays there until I manually stop the server.

Updated to: emby-server-synology_4.5.4.0_x86_64.spk

Rebooted several times to see if fault would clear.

Previous version (emby-server-synology_4.5.2.0_x86_64.spk) I had also did some weird things and would not work properly but I gave up and left it for months.

This version just fails to update anything even though I can play media that's listed.

DS918+ Log is attached.

Hi there, how have you configured your libraries in emby library setup?

[Mark-Ev 0]

Luke,

Not sure what exactly you mean but here is what I think you're asking.

I have two libraries, Movies and TV shows

Under "Server" - > "Library" - edit selected under each library;

Folders for "Movies"

/volume1/Emby

\\DS918plus\NAS\Video\MOVIE RIPS

Folders for "TV shows";

\\DS918plus\NAS\Video\TV Series

I would assume this System.OutOfMemoryException could be a factor.

That log appears to only show one library.

Info LibraryMonitor: Watching directory /volume1/Emby

Why is your data path configured as a Library? That path is only for Emby programdata.  So you are creating a infinite loop on itself if I am reading this correctly.

@Happy2Play excellent catch ! that's why i asked about the libraries because I expected we'd find something funny like that going on.

[Mark-Ev 0]

Happy2Play,

It was a while a go (1yr?)but my recollection is that it was a default directory. I did not want to move the media files to the Emby directory so I added my own library directory and gave Emby full access under the NAS User Control settings. I left the "Emby" directory there.

Unless during installation I was asked to select a destination?

Funny that it used to work OK until I upgraded to a new version.

I will try to remove the directory reference.

As for RAM usage, the DSM Resource Monitor says RAM is OK at 11%.

Thanks for your help.

 

[Luke 37106]

At some point you must have added that folder as an emby library folder, which is not good because that's also the server's data folder.

I would suggest removing it and then running a full library scan.

Thank you very much guys. Looks like it's fixed!

Thanks for the feedback.
