Hi,
I have a watchOS app which is able to control Sonos speakers. So people set it to stay active for 1 hour. Unfortunately, the system kills the application every time after 5 to 15 min. I have made many system diagnosis and the pattern is always the same.
- Carousel decides that the app must be suspended.
- runnungboardd suspends the app.
- filecoordinationd kills with SIGKILL because it detected it has been suspended.
- launchd reports that the app has been killed.
The issue is that I don't understand why Carousel wants to suspend the app. I have disabled all animations while the app is in Always on mode. The app does not perform any operations.
If anyone has any idea on what do try, I would be glad for help.
Here are some of the related logs. There are thousands around that but I could not deduce anything useful from them.
The app gets suspended and then the filecoordinationd decides to kill it. But why is it suspended ?
Just before, the app invalidates the timelines. But the timelines here are from the Backlight service.
