是这样...主机是用amzon的虚拟机...炮了TOMCAT..httpd...

    所以说要找到主要问题点...帮帮分析..大概的问题点...前说的JAVA会不是因为系统出现问题时重复KILL java报的信息呢???

chenyx

没用过amzon的虚拟机,你的那个虚拟机的内存多大,跑的linux的版本是什么,tomcat的版本等等信息,以及2楼让你提供的其他信息,贴上来吧

    我觉得是你的jsp程序的问题,导致系统内存耗尽,所以kill jiva主程序

楼主检查下宕机的那个时间段,apache和tomcat的日志,看看能不能发现什么线索.

现在内存如土豆价格时代（最近白菜涨价了，发现土豆便宜点），还3G内存跑。

1. 增加内存

2. 检查应用程序，优化应用

3.做系统监控

    兄弟,他的那个不是物理主机,应该是租用的VPS之类的虚拟机

你JVM开多大内存啊？
