Answer 1

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。
