LG webOS 'Out of Memory' Error

Why does my LG webOS keep rebooting with the message "This app will now restart to free up more memory."

The most common reason for this error message to appear which, causes recurring automated reboots of the screen, is because the content files are too large in terms of file size and/or resolution.  Please re-size your content to match the resolution of the screen or zone.  Not only will the webOS SoC screen perform better, the content will also look much better as the content will be designed to fit rather than being scaled.
