When I try to add a new version of my app in appStore - An error has occurred. Try again later - Error is showing. Not able to create or do appStore update for my existing app.

It seems context getting cleared in multithreading when use with core data. Thread 3: EXC_BAD_ACCESS (code=1, address=0x33) #5 0x00000001ad576390 in -[NSManagedObjectContext(_NSInternalAdditions) _forgetObject:propagateToObjectStore:removeFromRegistry:] ()
