ios - com.apple.root.default-overcommit-priority 中的不明崩溃

Question

只是非常不清楚(至少对我而言)内存崩溃

Crashed: com.apple.root.default-overcommit-priority
EXC_BAD_ACCESS KERN_INVALID_ADDRESS at 0x4086ec0000000000

其他线程似乎没有做任何有趣的事情，他们中的大多数什么都不做，但 UI 可能处理了一些东西但是在了解堆栈跟踪之后我不知道发生了什么。

如果您知道它是什么，或者至少知道如何处理它，请分享您的知识。

谢谢!

"Memory overcommitment is a concept in virtualization that covers the assignment of more memory to virtual computing devices than the physical machine they are hosted on actually has."

所以你可以看出这是一个内存问题。检查您是否在某处使用了大量内存。
