SpringBoard or FrontBoard crashed

My app may triggered a iOS bug. When the main thread is stuck, that make SpringBoard or FrontBoard reboot(apple icon displayed). I can't reproduce this bug, It does not appear often. Here is my app ips file and SpringBoard log.

What's kind of code can reboot SpringBoard?

SpringBoard crash log:

Well, that’s not good. Critical systems services like this should never crash. The next time you see this, please trigger a sysdiagnose log as soon as you can after the event and then file a bug with that log.

Please post your bug number, just for the record.

For more info on sysdiagnose logs, see our Bug Reporting > Profiles and Logs page.

have the same problem

These system processes are very complex so it’s possible that a similar-looking crash might have a completely different cause. Still, my advice hasn’t changed on this front: If you encounter a crash like this, file a bug about it with all the info you have available. At a minimum this should include a sysdiagnose log, but if you have any way to reproduce the issue, that’d be great.

Please post your bug number, just for the record.
