What does this crash log means?

I have already done some research on identifying crash logs but couldn't find solution:

Here are my references:

http://www.raywenderlich.com/23704/demystifying-ios-application-crash-logs http://developer.apple.com/library/ios/#qa/qa1747/_index.html How to view crash report on xcode 4.2

I do come to know that it is because of Memory Issue but how to find that particular? In my project there are 200 files also there are 4-5 third party libraries are being used.

Here is crash log:

Please let me know how to find cause out of this.

If my application is crashing at random point of times, still can it be possible to upload on AppStore? Will Apple allow such application?

Edit: The major problem is application is not crashing over simulator, it does only on devices. Also on device, when we debug the app, it crashes on curl library code, which is working fine since first day. Then how come sudden crash occurs in application?

If your application is crashing randomly then you need to analyze your code. That you can do in XCode only.Open your Project in XCode and in Product menu you will find the Analyze option (cmd+shift+B) .make sure you have selected "iOS Device" before analyzing it.

other than this you can use the this link:

apple will not accept your app if it is crashing.
