This is indeed an endless loop and it is intended: The rescan interval for the default folder is 60 seconds (which in effect is a random time between 45 and 75 seconds). So looks like Syncthing is doing exactly what it should in these logs: It scans your folder every minute. As you probably have no changes, it finishes in almost no time (<1s).
