 Syncthing is fairly hungry for file descriptors and the default limits may be

+Note that in addition to ulimits, there is a kernel-level file descriptor limit
+which may also need to be adjusted. This limit is managed through the
+kern.maxfiles sysctl(8).

+Another option is to turn off the file watcher and use only periodic scans.
