It appears that my media is not getting scanned correctly. Any pointers for what I should do? Thank you. Log.txt

Hi, I have just updated the emby server, since it does not want to do scan library.

Hi I'm running Emby-server v3.1.63.0 (beta) on Debian 7 and tried before with latest release version with same problem. When scanning Library, emby-server stops after few seconds and display : Scan Media Library Failed - Constraint failed columns itemid - AncestorId are not unique. Movies and Musics materials are stored on another server (Unix). So I'm using 2 mount points : /mnt/Movies and /mnt/Musics. All was running great for 2 years ! I tried to uninstall emby-server and re-install : same problem. I tried to remove files and folder in admin user home folder : same problem. If I add a new media Library for Films as "Personal Video" type, Library Scanning works ! With Music media, if create a Library as "Undefined material" , error message is : Scan Media Library Failed - Constraint failed columns itemid - UserDataKey are not unique. Really strange behaviour. Is it a version problem, a database problem ? Many thanks for your help. Best

Hi All, I'm a bit stuck on how to trouble shoot this issue I have got since the last server update. Not sure if it is related to the update or just something random that has gone wrong with the database or xml data somewhere: I did have chapter extraction on, so I have tried disabling that with the scan. Still fails around 60% with the same error. Chapter extraction works by itself. Any suggestions on how I might track down the root cause is greatly appreciated! I have attached my latest logs. Thank you. server-63581119004.zip
