I have to be _very_ careful with the updatedb deamon, I know it is  
programmed to execute every night at 4 am, but if you don't give it time 
to execute, it'll execute the next time the machine is on, I haven't 
seen this process come up when playin UT2004 (thankfully) but it does 
happen in other games (like NWN), when that process runs, it literally 
kills performance. So my recomendation would be to make sure you execute 
that process when you are away from your computer or at a convenient time).
