Application crashing in thread named com.apple.CFURLCACHE_work_queue

Question

My application crashed in a thread named com.apple.CFURLCACHE_work_queue, and the crash logs do not seem to give any hints for me to find the error or error = (

any idea or clue why this is happening? I suppose this has something to do with NSURLCache, but I am not manipulating or even creating this object in my application.

I am using Xcode 4.5 GM - I know that it has not been publicly released yet - and AFNetworking 1.0RC3 for network communication and uploading image data

From the view of things in numbers 10 and 11, he ran out of memory and threw an exception, perhaps as part of a statement.

You will probably find exception information in the console log for the device. If you can connect your device to a Mac, you can access this data in Xcode. Devices do not store a lot of console data, so it’s best to get a log very soon after detecting an error.
