Question

我们的应用程序由于记忆而崩溃，但这些数字没有意义......

我们使用XCode内存，Activity Monitor仪器和VM Monitor仪器跟踪应用程序，它们都显示相对较低的内存使用量（200-300 MB）。然后应用程序崩溃，没有看到任何内存增加。当我们在XCode中收到内存错误时，内存使用量仍然显示为200-300 MB。

现在，当我们查看崩溃日志时，数字也不会加起来：

你可以看到rpages是166,401（总是相同的数字，我想这是每个进程的限制），但是生命周期最大只有82,558页。这是什么意思？如何使用的页面高于生命周期最大值？考虑到崩溃前一切似乎都很好，有关如何调试这个的想法吗？
