P4 3.6
内存 1G
硬盘 SCSI 140 G 分区情况 /boot(500M) /SWAP (2048M) /（剩余全部磁盘空间）
服务器是新的HP全新配置
服务器的WEB配置情况：红旗LINUX5.0服务亚洲版＋TOMCAT5.5.17+MYSQL5.0.22+JDK1.5.0.6
TOMCAT和 MYSQL以及JD的安配置过程我就不说了
现在的问题是：开发组十几个人点击，频繁刷新（遨游浏览器有个自动刷新的功能^_^，我们每台机器开了网站上15个左右窗口，设置成每隔10秒自动刷新），结果不到十分钟就TOMCAT就宕机了
终端显示错误如下：
严重：All threads (150) are currently busy, waiting. Increase maxThreads (150) or check the servlet status
程序是用的hibernate + spring
Connector port="80"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
debug="0" connectionTimeout="20000"
disableUploadTimeout="true" />
我试图把maxThreads改为999
Connector port="80"
maxThreads="999" minSpareThreads="25" maxSpareThreads="999"
enableLookups="false" redirectPort="8443" acceptCount="999"
debug="0" connectionTimeout="20000"
disableUploadTimeout="true" />
再测试 ，十多分钟后问题依旧 报错如下：
严重：All threads (999) are currently busy, waiting. Increase maxThreads (999) or check the servlet status
这个已经最大了 web server允许的最大连接数还受制于操作系统的内核参数设置，通常Windows是2000个左右，Linux是1000个左右。也就是说maxThreads最大连接数，不能高于一千。
并且我在catalina.sh中配置了JAVA_OPTS='-Xms256m -Xmx512m'最大内存
MYSQL的配置文件 /etc/my.cnf

问题 ：大家看是什么问题，是TOMCAT的配置问题，还是MYSQL的问题
还是程序的问题，我们好象是用的tomcat自己带的数据库连接池，没有用到
MYSQL官方网站上的连接池的jar文件，不知道是不是这个的问题。
