(iOS) iPad app Crashing Randomly on Start

I have an iPad app out in the field (enterprise distribution) that randomly stopped working (after about 150 uses). It loads the black screen like its about to open but then flashes back to the main screen.

• No other apps are installed on the iPad.
• iPad is not jailbroken.
• iPad software has not been updated since install.

The app remains in the running list, but will not open. After resetting the iPad and reinstalling the app, it runs fine again. The crash report is as follows:

This is all the information the report contains.

We've never been able to reproduce the crash on the simulator.

Any ideas? Can't send this back out until we make sure the error is fixed. Thanks,

The system is probably killing the app because the provisioning profile has expired. If you can get access to the old app (e.g. by syncing with iTunes and then doing Reveal in Finder on the app) then you can find the provisioning profile inside the app as embedded.mobileprovision which you can inspect to determine if it has expired.

Check your startup sequence carefully. Perhaps some config file you are reading is corrupt or cannot be deserialized to a data structure (e.g., NSDictionary) properly.

I've had this happen to me.

I came across this issue today and finally I adjust the provisioning profile of my app then the strange crash disappeared. So you can try to this method to solve the problem. PS:My crash log is same as the JJ's Good luck.

1.make sure the device identifier key has been added in your IDP's distribution profile,
2.download that profile and drop on to Xcode
3.clean, build/archive you app project
4.Give users a URL to download(install) that mobileprofile file
5.enterprise distribution you app.

Try to add to your project setting not just armv7 but armv6 also.

Does it occur always after 150 or more uses?
If yes then checkout what all parameters get affected when it's used for large number of time. I had faced similar problem but my app was using core data.I was saving some value and by mistake I had set the type to INT 16. and it used to crash whenever value passes 2^15 for ios 5 and above. Secondly , are you able to re-start app after quitting the app from background or you have to delete the app and re-install it to fix the problem?
