I have an app that receives remote notifications. My view controller that is shown after push has a tableview. App crashes very randomly (1 in 20 tries) at line setting frame:

if (!myTableView) {
        NSLog(@"self.myTableView is nil");
    }
    myTableView.frame=CGRectMake(0, 70, 320, 376);

This only happens when i open the app, then open some other apps and then receive the push notification. I guess it has something to do with memory. I use ARC (ios 5). The strange thing is that nslog is not displayed, so tableview is not nil.

Dealloc is not called because it is not logged:

- (void)dealloc {

NSLog(@"dealloc");

}
