I enabled MasonX::Profiler as you suggested. Here is the relevant log entries

RT::Config::__ANON__('RT::Config=HASH(0x14eab98)', undef) called at /opt/rt4devel/sbin/../lib/RT/Config.pm line 1159
RT::Config::PostLoadCheck('RT::Config=HASH(0x14eab98)') called at /opt/rt4devel/sbin/../lib/RT.pm line 199
RT::Init('RT', 'Heavy', 1) called at /opt/rt4devel/sbin/rt-server.fcgi line 126

==> /var/log/httpd/error_log <==
=Mason= localhost - /index.html BEGINS {{{
=Mason= localhost -     /autohandler {{{
=Mason= localhost -         /Elements/SetupSessionCookie {{{

At this point there is a 3 minute (I upped it to see if it would ever finish) wait until fcgi times out and throws the internal server error.

TONS more Mason logs

Not sure what this really tells me.

Our DBA is looking into the database side. Apparently It is blocking itself going against the 11g database. Sessions are blocking other sessions. We are looking into any possible database parameters new to 11g that cause this behavior to be different from our production 10g RT database.
