tomcat 内存溢出以及临时解决办法

  现象描述:

  TOMCAT进程还在,但无响应。导致WEB页面无法浏览。。。。

  查看日志:

  /usr/local/Tomcat_Front/logs/localhost.2007-07-01.log

  #vi localhost.2007-07-01.log

  查询关键字“OutOfMemoryError”,结果如下:

  2007-7-1 22:47:22 org.apache.catalina.core.ApplicationDispatcher invoke

  严重: Servlet.service() for servlet 51auto threw exception

  java.lang.OutOfMemoryError: Java heap space

  2007-7-1 22:47:22 org.apache.catalina.core.StandardWrapperValve invoke

  严重: Servlet.service() for servlet default threw exception

  java.lang.OutOfMemoryError: Java heap space

  暂时解决方法:

  加大-Xmx512m为-Xmx1024m。
