First sync taking days on synology nas, taking 1GB RAM, stuck at 500 items out of 769

You might be right, I’ve hit the “Override changes” on the master, and now, I’m seeing a lot of logs on the slave :

[3767M] 17:14:06 INFO: Puller (folder "music", file "some/folder/relative/path/file.flac"): shortcut: chmod /some/folder/absolute/path/file.flac: operation not permitted

I don’t know what it’s trying to do, and when I lok in detail at some of the files in these logs, I se this :

ls -al file.flac
-rwxrwxr-x    1 toxic    users       651090 Mar 24  2007 file.flac

I’m running the syncthing program with the “syncthing” user, and in the /etc/group file, I have this :

users:x:100:syncthing

So I believe it should be ok… I do not understand what’s going wrong here…
