Hi,
ubuntu 9.04
Xeon Processor
4GB memory
LDAP AD authentication windows 2003
upgrade from 3.2.2 to 3.8.4 everthing appears to be ok.
server is running RT3 and nothing else.
Problem:
When there is a period of inactivity, particular for a few hours, and when
a user logs back in, the apache error logs indicates
"Mon Jul 27 10:48:21 2009] [notice] child pid 2894 exit signal
Segmentation fault (11"
the webpage became white and multiple refresh of the page bring rt website
back to the logon page.
When a user logs back in and apply the "Refresh this page every X minutes,
than there is no segmentation fault on the apache log and all appears to
be 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
after "segemntation fault" for me to properly diagnoise this.
I have played with the numbers on the apache2 and mysql links below and
still can't resolve this.

http://wiki.bestpractical.com/view/FAQ
below are my httpd.conf file and RT system configuration (santized) -
hope someone can shed some light on this.
Appreciate your assistance!
