我的iPad应用程序在发布时崩溃了。仅由一些用户报告。重新安装应用程序似乎使它工作。

Elapsed total CPU time (seconds): 380.760 (user 380.760, system 0.000), 98% CPU 
Elapsed application CPU time (seconds): 0.061, 0% CPU

我的后台任务代码是

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    /*
     Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
     If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
     */
    NSLog(@"Background time remaining in didEnterBackground:%f",[[UIApplication sharedApplication] backgroundTimeRemaining]);
    __block UIBackgroundTaskIdentifier backgroundTask;
    backgroundTask = [application beginBackgroundTaskWithExpirationHandler: ^ {
        [application endBackgroundTask: backgroundTask];
        backgroundTask = UIBackgroundTaskInvalid;
        NSLog(@"Background task Completed.");
    }];    
}

基于Xcode文档，我看到这种异常类型意味着看门狗正在终止应用程序。我无法重现崩溃并且没有设备控制台日志。请帮助分析此崩溃日志。
