使用iOS 4.3模拟器的iOS SIGKILL带有无趣的回溯

“只是把自己的事情,iOS应用程序运行在模拟器中,没有做任何非常有趣的事情,只是在视图控制器之间移动…然后暂停…和KABLAMMO!

我立刻看了所有线程的回溯(见下面),但是我没有看到任何特别有意义的事情:

(nb:在Debug Navigator中,线程7被列为com.apple.CFSocket.private,线程4被列为WebThread。)

我想操作系统杀了我的应用程序,但我不知道为什么。

内存过多使用? 那么,我们在模拟器(但是,是的,我已经很谨慎 – 在debugging过程中没有发现内存警告)。

阻塞主线程? 呃…不是我所知道的! UI发生时似乎足够敏感。

运行日志中有趣的东西? 没有…相当日常的事情,但就是这样。 :\

进一步的洞察力和想法赞赏

看到这个问题的类似(相同?)ish。
