碳继电器消耗CPU-EAGAIN（资源暂时不可用）？ Python 2.7.3 [twisted，13.1.0版] 森多姆

顶部显示，碳继电器正在消耗80，90%的USRCPU。从远处看：

奇怪的是：即使重新启动服务，每次运行strace时它似乎都卡在FD7上。这是否意味着此fd未正确清理

我增加了打开文件的数量：

/proc/2891/限制

然后下降到约50%

我的问题看起来与此类似，但由于我们有几个处于TIME_WAIT状态的套接字，我认为启用tw_循环没有帮助。关于tcp_syncookies，我在系统日志中没有看到任何相关消息

这是我在调试模式下尝试启动碳继电器时得到的结果：
