下午检查apahe的error_log的时候发现大量：

[Tue Jul 29 14:35:39 2014] [notice] child pid 22397 exit signal Segmentation fault (11)

[Tue Jul 29 14:35:57 2014] [notice] child pid 22528 exit signal Segmentation fault (11)

这是内存泄漏了，网上一通搜啊，都没有找到想要的东西。

搞了半天突然发现网上有个地方不能跳转了，发现一点击这个链接就出现‘child pid xxx exit signal Segmentation fault (11)’的消息了。

查看程序也只是一个"header(‘location:$url‘);" 而已，在这个代码后面加个exit； 就ok了。奇怪了之前也是好的 怎么突然就不行呢...  之后在思考吧
