服务器上的tomcat突然停机了

服务器上的tomcat突然停机了,我怎么起都起不来,实在没有办法了,只好机器重新启动,机器重新启动之后tomcat就能起来了,怀疑可能是内存溢出,但是还要观察一段时间......

两小时后......

死人的怪事情

大家说怪不怪:

今天我的服务器突然给停机不干活了,我我以为只是意外的停机,没有当回事,但是我重新启动机器后,竟然没有到半小时网站又不能访问了,这下我急了:立刻远程登陆到服务器查看tomcat的日志:

部分日志如下:

椐本人经验,这个应该是要么没有打 sql补丁,要么是数据库的获取连接的信息错误,这个网站是我一个人开发的,前前后后我自己十分的清楚:补丁我肯定打过,连接信息我从来没有更改过,以前一直是这样的连接的,也没有出现这个问题,怎么突然会这样??
想了很久>>>>>>
无果......
实在无奈,只好再将sql补丁重新打一次,重起竟然好了>>>>>>>>>>>
狂呼三声,以为一切将顺利......
半小时后.....
网站又无法上去....
重复此前动作,又好了...
这下我就郁闷了,补丁难道自己会自动卸载??

苦思无果....


如果有哪位朋友以前碰到过类似的问题请赐教.
