Need Help on "threads/110306: apache 2.0 segmentation violation when calling gethostbyname"

[Jeff Mo]

Hi ,

Can anyone nicely explain a little bit about what does "ServerName is not
defined
in httpd.conf." mean in the following sentence from bug description?

"The problem happens if php module is loaded and ServerName is not defined
in httpd.conf."

Thank you very much
Jeff
