web服务器问题，页面打开非常慢

livelin

一台web服务器, 运行的是前端apache2，后端是jboss跑应用，日志是mod_jk一直有报错信息，到一定时间后页面打开就非常慢，重启才能正常
页面打开很慢的时候，netstat看到的非常多的timeout，close_wait等非正常连接
modjk日志如下：

worker.node1.socket_timeout=100
worker.node1.connection_pool_timeout=10

把这俩个时间设置大点看看

是打开JSP的网站慢呢？还是PHP和HTML的慢呢？

livelin

是jsp的页面慢

按xiaoyu说的增大了两个timeout的值，好像还是老样子

如果只有jsp有问题，看看数据库正常不，

看下你的tomcat日志是否有异常表现

livelin

谢谢以上几位提供的建议

目前就mod_jk日志中老出现上面的异常，其他日志看了没有问题。

网站还是比较慢

livelin

现在看到的情况是TIME_WAIT的链接数很多 从50-280，而且变化很快， 我是每5s抓一下来看的

     53 CLOSE_WAIT
     56 ESTABLISHED
     28 LISTEN
     14 SYN_RECV
     57 TIME_WAIT

其他状态的链接数变化不是很大，这样的话应该调哪个mod_jk的timeout值呢

守住每一天

问下LZ 问题解决了吗？
