急急急 resin-ee-2.1.12 + oracle9i 死机----->>>

[rak]

几乎每天死机一次，是电脑死机：(((
每天都要重启动一次电脑，我都快疯了，
大家帮帮忙啊...，，，

网站访问量并不大，而且内存512 ，我查过，
java占用的内存最多的时候只有80不到

有 java.lang.NumberFormatException
java.lang.IndexOutOfBoundsException
java.lang.NullPointerException
的错误，但我观察过，这些并没有让resin死机，
死机的原因现在还不清楚，

各位大侠帮帮忙啊。。。。

程序错误 仔细检查一下你的程序

java.lang.NumberFormatException: null

一定是 页面中想得到一个 对象 结果你得到对象为空 说明可能的情况：

1。 格式错误

2。 没有正确传递参数

仔细检查一下

ArrayList.jav UserLoginHandler.java NewQuestionHandler.java

你的程序编译的时候肯定没有问题 ：）

但是不严密！

[viano]

补充：

例如 某个程序你想得到一个 int 类型的数据 结果你的用户

输入了 字符串 如果你没有扑捉 NumberFormatException 异常

那么系统则会产生这样的异常。

多谢两位，只是在死机重启之后，我查日志，发现，最后一次的日志都是正常的，错误信息也没有，不知是不是以上原因使机器死机，大家还有其它的诸如这类的错误解决方法吗。???
