I have this error in my apache acces log.
我的 apache 访问日志中有此错误。
I work with apache 2.2 and tomcat 7. In the access file i see that apache send request to tomcat but tomcat can't treat them all. And when the error occures, i must restart tomcat to make my application work.
我使用 apache 2.2 和 tomcat 7。在访问文件中，我看到 apache 向 tomcat 发送请求，但 tomcat 无法处理它们。当错误发生时，我必须重新启动 tomcat 才能使我的应用程序工作。
I have 2 j2ee applications application on tomcat. That application use connexion to posgres database via jdbc connexion pool. I see in my application log their is at least 4 free connexions. So i don't think there is trouble with database.
我在 tomcat 上有 2 个 j2ee 应用程序。该应用程序通过 jdbc 连接池使用连接到 posgres 数据库。我在我的应用程序日志中看到他们至少有 4 个免费连接。所以我不认为数据库有问题。

有人知道是什么导致了这个错误吗？提前谢谢你！

The settings for the packet data transfer needs to be increased which is now low and the ab tool is not able to serve any data after the completion of the mentioned packets. You can change the configuration as below and then can enjoy running ab tool for your applications. On Ubuntu Server you can find them in /etc/sysctl.conf
需要增加数据包数据传输的设置，该设置现在很低，并且在上述数据包完成后，ab 工具无法提供任何数据。您可以更改如下配置，然后就可以为您的应用程序运行 ab 工具了。在 Ubuntu Server 上，您可以在 /etc/sysctl.conf 中找到它们

尝试添加以下 apache 参数，the virtual host section其中应该在httpd.conf文件中或根据您的服务器配置的任何其他位置
