为什么我的apache2总是提示exit signal Segmentation fault (11)

gig2600

系统是RH8
apache2.0.49+php4.3.6
在浏览一个php页面的时候,总是出现
exit signal Segmentation fault (11)错误
导致apache2子进程被杀掉,无法提供web服务

也尝试过php4.3.4版本
依旧如此请问是什么原因呢?
我的php是这么配置的
./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache/bin/apxs --with-oracle=/export/oracle/product/9i --with-oci8=/export/oracle/product/9i  --with-gd --with-jpeg-dir=/usr --with-png-dir=/usr --with-zlib-dir=/usr --with-xpm-dir=/usr  --without-mysql

调用的php页是读取oracle数据库的记录.

多半是那个 php 脚本的问题，比如向一个没有分配内存的变量写东西，等等。

子进程被杀掉，应该不会影响 web 服务。一个子进程死掉，apache 会再生成新的。

生成一个就杀死一个
总是segmentation fault.

下面是gdb的结果

Program received signal SIGSEGV, Segmentation fault.

从这个 post: http://www.geocrawler.com/archives/3/254/2003/8/0/10594569/

作者的问题是没有在 apache 的运行环境里设置 ORACLE_HOME 这个环境变量。不知你的有没有设？

非常非常感谢
