perl的内存管理问题。<BR><BR>大家好，<BR> <BR></DIV>
<DIV class=Ih2E3d> 我用perl的HTML::DOM
解析约7万个HTML页面内容。结果发现没解析2,000个左右，脚本程序就出现一次崩溃。错误信息为内存占用过多，被操作系统杀死。<BR><BR>
我不知道如何去DEBUG一个perl脚本，跟踪到底那部分没有释放内存。但是可以肯定的是我的程序是运行一个sub foo()循环，这个sub里的new
Object()都被我调用过object->close()，也就是文档里说的destroy操作。为什么持续运行程序，内存暴涨，从10M一直上升到580MB然后被操作系统杀死。。。<BR><BR>
能告诉我如何去调试一个perl程序, 或者直接找出那里出现内存泄露吗？ 或者还是perl的内存管理释放内存的时间太慢？？？<BR><BR>rorot
