-----------------------------
Summary: IOS 7 Phonegap crash when rendering images
Key: CB-4987
URL: https://issues.apache.org/jira/browse/CB-4987
Project: Apache Cordova
Issue Type: Bug
Components: iOS
Affects Versions: 3.0.0
Environment: IOS 7, iPhone 5s, Cordova 3.0
Reporter: Vunda Von
I have an infinite scrolling list in which the user scrolls to the bottom and
new items load from the database. I am properly removing any object and image
from the DOM however that is not in view. I unload images by setting their src
to an empty string. I have monitored with Instruments on the Mac and I can see
the memory constantly being collected and never peaking about 25 MB. My
problem is random, when rendering a new page from infinite scrolling, if it is
heavy with images, it crashes. Here is log from the thread that crashed:

Images are about 900px width and resized with css to about 400px. There are no
shadows or fancy css3 effects on the images.
