为何在启动WebSphere后，ps -ef 里会显示很多个java进程？

为何在启动WebSphere后，ps -ef 里会显示多达10多个进程？
ps -ef|grep WebSphere命令的执行结果如下：

db2inst1 2585 --------------------编程问答-------------------- 造成这些线程占用内存居高不下。
而且我的程序运行后这些Java进程的内存占用会稳步增长，直到系统崩溃，这玩艺怎么这么烂！ --------------------编程问答-------------------- 你的WebSphere是什么版本的?这种情况只有在比较旧的版本里才会出现.V5 以后应该就没有了.
另外,这些Java进程都是进程25756的子进程,这时要检查一下这个进程25756是什么,和它在干什么了.
