一天死了三次！！！
有人给我发的：

附件中是一些weblogic关闭的原因,我想下面这段说明可以试一试.

由于在运行一段时间jsp程序后，weblogic 的内存会有一个缓慢的增长，这样也会导致内存溢出，为了避免这总现象的出现，最终的解决方法是：编写一个servlet程序，在启动服务器的时候，启动一个这个servlet，每隔20分钟运行在服务器端运行一次，来定时回收内存。

------------------------------------------------------------------------------
实际上在虚拟机很忙得时侯运行gc是没有用的，gc本身就很不可靠

谁有比较好的解决方案？大牛都到哪里去了？

升级为weblogic7或8?
用的是Weblogic6.1就是自带的jdk

换成jrockit？不知道有没有合适的版本：（

会不会因为程序的原因造成的？

有时侯服务器变得很慢，重起一下就好了
