TOMCAT进程假死问题
我公司现有一台WEB服务器，架构是:linux+nginx+tomcat+mysql
具体软件版本：
linux:RHEL5.4
NGINX：nginx-0.8.54
tomcat:apache-tomcat-6.0.18
mysql:5.0
目前的主要问题是，当tomcat的本地连接数达到100时，就无法通过互联网络访问WEB SERVER。当把TOMCAT重启后，服务器又恢复正常。
通过netstat -an如下：

udp 0 0 :::5353 :::*
此时，内存、CPU利用率都不是很高。我搞不懂这是怎么回事，请高人指点一下。
其次我想了办法，写一个SHELL脚本，当进程达到100时，自动重新启动tomcat,但是由于自身SHELL水平有限，所以，请大家帮助我完成这个脚本，脚本如下：
#!/bin/bash
tmp=`netstat -an|grep 127.0.0.1:8080|grep CLOSE_WAIT |wc -l`
tmp=$tmp>100
if [ 0 ]
then
/usr/local/tomcat/bin/shutdown.sh
sleep 5
/usr/local/tomcat/bin/startup.sh
else
echo "do not need to restart the tomcat programe" >> tomcat_monitor_log.log
fi
这个脚本的执行结果总与我的实际想法总是不一致。这高人帮我看一点问题出在哪里了？
先谢谢了!

此时，内存、CPU利用率都不是很高。我搞不懂这是怎么回事，请高人指点一下。
其次我想了办法，写一个SHELL脚本，当进程达到100时，自动重新启动tomcat,但是由于自身SHELL水平有限，所以，请大家帮助我完成这个脚本，脚本如下：
#!/bin/bash
tmp=`netstat -an|grep 127.0.0.1:8080|grep CLOSE_WAIT |wc -l`
tmp=$tmp>100
if [ 0 ]
then
/usr/local/tomcat/bin/shutdown.sh
sleep 5
/usr/local/tomcat/bin/startup.sh
else
echo "do not need to restart the tomcat programe" >> tomcat_monitor_log.log
fi
这个脚本的执行结果总与我的实际想法总是不一致。这高人帮我看一点问题出在哪里了？
先谢谢了!
