This problem appears at random times throughout the day. I can run my simulations perfectly fine, not change any settings, and then suddenly the instruments will crash. I have tried ‘killall node’ and ‘killall instruments’ in the command line, but this does not help. Neither prelaunch nor running test cases will work when this problem appears. Has anyone else had this problem? I have seen other similar topics, but I have not seen this in users that have successfully built an app and tested it multiple times before this appears. This happens every day, and I would love a solution to this problem. I am using appium 1.4.13 because this seems to run our app well.
