Not sure if this is an iOS 8 issue... I called Apple to get AppleCare on my iPhone 6. They said they would first have to run a diagnostic test to make sure there wasn't any issues with the phone. Well the test came back saying that I was almost out of memory. And it seemed that a program called "mediaserverd" was using up all the RAM. I'm not sure why that is happening. I downloaded a program to monitor system activity. That program called mediaserverd was indeed there . It also says I'm using 867mb of ram out of 987mb. Any ideas? None of my apps were open at the time, I don't have background app refresh on. And I tried doing a hard reset. The only thing left to do is probably a new restore, but I'm trying to leave that as a last resort.
