已经修改了catalina.bat里set JAVA_OPTS=-Xms64m -Xmx256m

内存泄露了，你电脑多大内存的？参数在jre上设置比较管用，其他的什么改tomcat参数啊，eclipse设置啊我都用过不太管用。
window-preferences-java-install jres 当前jre版本-edit--default VM arguments加上这句
-Xms800m -Xmx800m -XX:MaxNewSize=256m -XX:MaxPermSize=256m

这么搞。追问

公司小破本 2G内存 好 我试试

参考技术A 是不是物理内存用尽了，用资源管理器看看内存使用情况追问

物理内存73%

参考技术B 内存溢出？追问

怎么解决呢？
