Does the Pi write data to the SD card or to some sort of external storage? If the latter, is the Syncthing configuration file located on the SD card?
My experience with Syncthing on a Raspberry Pi has been that corruptions happen very often if you write to the SD card a lot. I have set my Raspberry Pi in a way that the Syncthing config and the synced data all reside on an external USB HDD, this keeps the amount of writes to the SD card low and helps avoid issues down the line.
