解决方案
你看一下tomcat挂掉之前的后台日志（不是你提供的log，是命令行中给的异常信息），有没有out of memory异常，同时看一下tomcat挂掉后，访问前台页面是什么结果，能访问但出错还是没有反应。如果是out of memory，可以增加tomcat启动参数，在%tomcat%/bin/catalina.bat文件中，在rem Guess CATALINA_HOME if not defined后面增加"set JAVA_OPTS=-Xms256m -Xmx512m -XX:+PerfBypassFileSystemCheck”,提升tomcat可使用的内存大小。
解决方案二：
之前我也遇到过同样的问题，可能和系统有关吧 尝试换下系统或者从做下系统看看呢
解决方案三：
如果是out of memory，tomcat 6也会有同样的问题，你也可以用上面的方法修改：）
解决方案四：
之前遇到过类似的问题，tomcat5.5好像是存在bug，后来直接更换了tomcat6.0，这个问题就不存在了。建议更换版本试试。
解决方案五：
看你的启动日子能看出什么呢，我最近用了个TOMACAT，过段时间直接CORE掉了，内存用完了吧，在bin目录里产生了几个core文件，用工具分析了,原来是堆栈满了。你可以看看有没有core掉。
解决方案六：
这些日志没用啊，估计内存爆掉了吧，直接把jvm给down了，看看logs目录下面有没有别的东西？
