--------------------编程问答-------------------- 应该是程序有问题阿，内存泄露 --------------------编程问答-------------------- 不知,帮顶 --------------------编程问答-------------------- 是不是进行了大数据量的操作
可以用jrockit 代的memleak工具查看内存中的对象，分析看是什么地方泄漏，
--------------------编程问答-------------------- 内存容量设置是多少呀??
够用吗? --------------------编程问答-------------------- 请看这里http://fronkx.blog.hexun.com/12407600_d.html --------------------编程问答-------------------- 有服务的话，打BEA的800电话。。。
