We are encountering frequent jetsams running MCPE 1.0.0 on iPad mini 1. I'm attaching JetsamEvent diagnostic logs that show moments where minecraftpe was terminated. When reading these, remember that it's the entries with "name" : "minecraftpe" AND a "reason" like "reason" : "vm-pageshortage" which are the reports where iOS terminated minecraftpe. These are generally showing on the order of 67000-73000 rpages, or 270-290MB, which is a lot for the foreground application on a 512MB iPad mini 1. It is likely that MCPE will need to reduce its steady-state memory usage to be able to sustainably play for long periods.

These games were three-device LAN games. Sometimes it was the device running the server that jetsammed (5 of 7), sometimes it was one of the other devices.
