Epoll模式错误

[kaibusi]

main.xml中改成Epoll模式，执行PurenessScopeServer。提示如下:

我用的是ACE6.3.0版本，按照说明文档已经把/etc/security/limits.conf文件各项设置6000，并已经重启系统生效。用的TCPtest例子测试的。
用select，poll模式都测试了，正常运行，只有epoll出现问题。
请帮忙看下这是什么问题导致的，谢谢

我找到原因了。 main.xml中 MaxHandlerCount="10000"，而我系统设置的最大是6000，超过了系统的上限值。把系统的上限值改大或者改小MaxHandlerCount，就不会出错误了。
