都到内核源码级别了啊

您好，看出问题了么，咱们方便给远程看下么

我们先看一下 看看是否有问题 等会同步给你

你好，有结果了么

看了堆栈信息io占用不太多 是符合预期的 目前从堆栈信息看 没有发现泄漏 grep MEMORY observer.log | grep IoControl 后面可以看IoControl的模块占用是否持续上升 也可以看observer.log中是否有-4013 内存爆的问题

observer.rar (2.3 MB)
还是存在-4013报错

看你发了官方悬赏 我们群里交流

好复杂

终于找到了类似的问题，感谢楼主的发帖，为排查问题提供了很大的帮助，不然真的不知道从哪里开始排查，太难了。

感谢楼主

我看看

内存一直不释放，租户内存100% 参考这个悬赏帖 是同一个用户提问

学习学习

感谢作者的整理和分享

干货满满，受益匪浅

收藏了

这个问题涉及到0x0和IoControl的平衡，根据我的经验，适当调整192会有帮助。
