[rt-users] Still slow, RAM-hog

	I've run through nearly every idea that I've had and I still can't 
make RT behave as quick or stable as I know it can.  (It consumes too 
much memory and then apache log file rotation causes apache to crash 
instead of restart.)

	Here is what I've tried.  Please make any "next step" suggestions that 
come to mind.

- Checked Apache's logs
- Reinstalled and/or upgraded all Perl libraries
- Reinstalled and upgraded mod_perl
- Reinstalled and upgraded Apache 1.3.x
- Enabled and checked RT's logs
- Enabled and checked MySQL logging
- Reinstalled RT 3.2.2
- Installed RT 3.2.2 on different server with fresh mod_perl, etc. 
installs and then have it reference the original MySQL server.
- Switch from mod_perl to FastCGI install.

	The switch to FastCGI was just today.  An interesting change did 
occur, even though it didn't fix the problems with performance and the 
inability to load our longest tickets.  Loading a long ticket would 
pause for several dozen seconds and then display a large chunk of the 
ticket's display all in one shot.  Another long pause, another chunk.  
etc.  However, one of our largest tickets wouldn't display any more 
than before.  Instead of just trying to render indefinitely, as did 
before, it paused for a little more than 2 minutes and then the page 
suddenly ended like this:  (final "good" section included for the sake 
of providing some context)

	The sudden change from "<TABLE CLA" to HTTP headers within the HTML 
source itself looks strange to me.  This is a ticket that has been 
giving me a lot of trouble ever since the RT 2.0.15 to 3.2.2 upgrade.  
I can't even make that ticket display completely.

	With all that I've done, I am starting to wonder what could be left.  
With the exception of dropping all the MySQL tables and starting over 
(without any of my still unresolved tickets!) I think that I've tried
