the webpage became white and multiple refresh of the page bring rt website

When a user logs back in and apply the Refresh this page every X minutes,

well.



There is no indication what the problem is on the logs /var/log/messages, 
/var/log/syslog, /var/log/rt.log /opt/rt3/var/log/apache2.error before or

below are my httpd.conf file and RT system configuration (santized) - hope 
someone can shed some light on this.

Appreciate your assistance!
