I am running into issues running a mapproxy configuration under apache on a CentOS 7 box. Here is the apache log with the error entry
[Mon Nov 24 21:32:33.980378 2014] [core:notice] [pid 31520] SELinux policy enabled; httpd running as context system_u:system_r:httpd_t:s0[Mon Nov 24 21:32:33.982164 2014] [suexec:notice] [pid 31520] AH01232: suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain.

The mapproxy configuration file runs fine under mapproxy-util serve-develop. I also tried mapproxy-util serve-multiapp-develop. They bot run fine. So, I am only running into issues when hosting on apache. The map configuration file does use a mapnik source, so I did add the "WSGIApplicationGroup %{GLOBAL}" entry to the .conf file.
Here is the content of my apache .conf file
WSGIScriptAlias / /usr/local/txwrap/mapproxy.pyWSGIDaemonProcess mapproxy-wsgi-daemon processes=8 threads=25WSGIProcessGroup mapproxy-wsgi-daemonWSGIApplicationGroup %{GLOBAL}<Directory /usr/local/txwrap> Options FollowSymlinks AllowOverride none Require all granted</Directory>

Any ideas on what might be going wrong here? 
Thank You,Vish
