So last night i believe i figured out the problem.  It has to do with a
Media monitor patch that was put in earlier for me.

The issue first started when I upgraded to fedora 8 on my old hardware.  It
was only 32bit but same case and pci cards.  At this time i was running SVN
self compiled.  i was seeing this spewed to the console when running
mythfrontend.

responded back with *hack* fix to make it stop.  This was then implemented
in ticket 4284.  For then all was fine.

I saw this after the fix:

here is the thread:
http://www.nabble.com/F8-errors-when-running-SVN-console-td14235447s15552.html

Then i upgraded my motherboard, CPU, and RAM.  I reinstalled F8 64 bit and
compiled SVN.  I had some issue compiling, when this happened I thought
maybe it was my compile.  So i installed ATrpms bleeding packages.  Still
not fixed.

Last night when i was looking the cmd line of the FE i was wondering what
the heck is /dev/sde-f?  Looking at hardware the only thing different in the
box from my other was it had 2 hard drives and a pvr-150 and the case an SD
reader on the front which plugged into USB headers.

I unplugged the SD card ports and those messages went away!  I just ran
mythfrontend all last night and the comp only used 600 of the 950mb of RAM
and no SWAP.

So my conclusion is Media Monitor must have been spawning new threads of
Media Monitor and not closing them properly, they just kept making new ones
and eating memory.  I'm going to put this in the ticket as well to see if we
can come up with a real fix.

I don't use the SD reader at all but some may for mythpictures, etc.
