WDT Timeout panics in 10.3.1?
Anyone else getting WDT Timeout panics in 10.3.1? My iPhone SE is getting about 4/week of these bad boys. Reported to Apple as bug 32063599. Seem to happen when running Google Maps and driving, or else while in a browser and scrolling down. iOS just freezes, then after 6 minutes or so, crashes and reboots.
Sometimes the OS recovers, after about a 5 minute freeze, without the panic.
First few lines of a typical WDT Timeout panic log follow, in case this might ring a bell with anyone.
Cheers,
Aaron
