解决方法:
如果你有Apache出现段错误是产生的core文件，最好对core文件作基本分析。如果你想让红帽支持帮忙分析数据，我们需要基础分析的输出，包括core文件本身和系统安装软件列表。以下是操作步骤：
1.列出/var/apache-dump/目录下的文件：
ls -l /var/apache-dump/
-rw------- 1 apache apache 71188480 Aug 16 13:48 /var/apache-dump/core.1333
2.用gdb去分析Apache core文件。一直输入回车直到出现'(gdb)'提示符，输入"where"。将gdb的输出信息拷贝粘贴，发给红帽支持。输入"quit"退出。
# gdb /usr/sbin/httpd /var/apache-dump/core.902

3.我们推荐你运行命令：
rpm -qa > /var/apache-dump/rpm-listing-`date +%s`
得到一个在产生core文件时后，系统已安装的RPM包列表，用于作为更进一步分析。
