I’m running Syncthing on 4 macs and to my knowledge this issue only occurs on one of them (12" Macbook running OS X 10.11.6).
Syncthing just stops synchronising, the effected computer is seen as not connected on the other machines. I can’t access the GUI via localhost:8384 but ps aux shows syncthing is alive. Running brew services restart syncthing doesn’t fix things, but running kill -9 syncthing_process_id then brew services restart syncthing does fix it until next time
Whenever this occurs I get this on the console regarding syncthing:
Service exited with abnormal code: 1
Service only ran for 0 seconds. Pushing respawn out by 10 seconds
This is particularly frustrating because I used to be able to rely on syncthing to work everytime but this is shaking my confidence
