我使用 Apache/mod_jk module连接jboss。但是运行一段时间后，出了点问题。
Apache :2.2.22 mod_jk:1.2.37 Jboss: 5.1.0 GA(集群环境) 操作系统:CentOS 5.2 x86_64 JDK:1.6.0_30-b12
这是 mod_jk.log 的一部分

注意:Jboss 运行良好。 telnet jboss 8009正常。如果您重新启动 jboss，它会再次运行。但是重启apache就没有用了。
有人遇到过这个问题吗？
最佳答案
我认为为 ajp 连接器设置连接超时可以解决您的问题。 这样的设置应该可以工作
<Connector port="8009" address="${jboss.bind.address}" protocol="AJP/1.3"
emptySessionPath="true" enableLookups="false" redirectPort="8443" maxThreads="1000" connectionTimeout="60000000" />
你在 server.xml 中配置它
有关此属性的更多文档，您可以在官方文档中阅读 http://docs.jboss.org/jbossweb/latest/config/ajp.html
