iOS6 app crashing in the background. How to decode the crash log?
Question
My app keeps crashing in the background. I do have some background tasks running that connect to a webservice. I have tried making those synchronous as well as asynchronous calls. Nothing seems to help. The maddening part is the crash log gives me no indication what exactly causes the crash. Apart from the fact that I am not ending my background task properly or within 600 seconds. How does the backtrace tell me where in my app and what thread caused the crash?
I am also not sure if the crash is because when the app was already in the background and then i called the webservice and it never returned (even though i am using synchronous right now) or is it because I was connecting to the webservice when the app went to the background and that is what is causing the crash.
I have read all SO posts regarding this. Also it never breaks on the simulator with app in the background and also with me turing off the network or turning it back on. Help please?

Notice the following part in your log:
Application Specific Information:
MyApp[6705] has active assertions beyond permitted time:
{(
<BKProcessAssertion: 0x1d569690> identifier: UIKitBackgroundCompletionTask process: MyApp[6705] permittedBackgroundDuration: 600.000000 reason: finishTask owner pid:6705 preventSuspend preventIdleSleep ,
<BKProcessAssertion: 0x1d56abb0> identifier: UIKitBackgroundCompletionTask process: MyApp[6705] permittedBackgroundDuration: 600.000000 reason: finishTask owner pid:6705 preventSuspend preventIdleSleep ,
<BKProcessAssertion: 0x1d56b580> identifier: UIKitBackgroundCompletionTask process: MyApp[6705] permittedBackgroundDuration: 600.000000 reason: finishTask owner pid:6705 preventSuspend preventIdleSleep
)}
It appears to be that you are calling beginBackgroundTaskWithExpirationHandler: without the corresponding endBackgroundTask: call.
Find out more about endBackgroundTask in the following link .

get the crash log to Xcode and symbolicate it there
how? one way (of the top of my head .... it might not be ideal)
- build your app as an archive and keep it in the organizer
- install that archived version on the device
- let it crash
- connect your phone and go to Xcode organizer, devices, crash reports
- click on re-symbolicate and it uses the app you archived to make it readable
