The lack of RAM (and I have to assume it is - since I've not had this issue at all on iPad Air 2) is causing this error far, far too often on my iPhone 6 Plus. At least several times a day (not to mention the incessant tab reloads) on more content-rich web sites. Just seems a real shame that a month after the iPhone 6 line is released with 1GB, the Air 2 is released with 2GB. Now, I fully understand that Apple is a business, and - after all - they need to sell us something next year. But this Safari "crashing" is significantly worse on the 6 Plus than any previous model. And before anyone says 8.1.1 will fix it - it doesn't.
