Syncthing app on sdfs volume?

[BartQ76]

Has anybody setup syncthing (syncthing.net) instance on the sdfs volume? I tried two times, each time encountered weird behavior. The app first creates temp files during syncronization process but on the sdfs volume it ends up with error 'file exists' for many files. The files actually exists, it looks like the app doesn't see them created before so it tries to create it again. I asked on the syncthing forum, with no luck. Do anyone have experience with the app?
