Our user reported lately that their devices were rebooted automatically after using our app for more than 2 hours , at the beginnig I cannot , I never seen an app will make the iOS system get rebooted, until our user send me a video prove it what they said is true.
And after that I asked them for the panic-full logs in their devices which indicate the device was rebooted unusually, the log shows that it's exactly our app's process leads to the reboot, OMG, I got shocked...
Our app is a live broadcasting app, most of our users encountered the reboot problem are when they finished broadcasting a live for a long time (maybe more than 2 hours) and close the room button, another infomation is that we add WebRTC.framework to our app lately, Our user's devices and system version vary, so maybe there is no relation with these factors.
I reproduce this problem once on my iPhone 7P (I boradcasted for 2 hours, my phone rebooted exactly after I clicked the close button of my live room), and the panic log in my phone is very similar with logs from our users. Here is part of my log, I put the full on pastebin: https://pastebin.com/Hh9TqZgh
