Because updatedb is flogging the disks. For me it is problem because whole machine "freezes" (no reaction on anything) for 2-3 minutes.... - and after 2-3 minutes it has load about 50-100 - I think that it has higher load (>100) when it "freezes" then after next 2-3 minutes situation repeates.... >Do a full "ps aux" listing and you'll probably see lots of processes in "D" >state, waiting for the disk head to seek across and read whatever it is >they are trying to read. In top I can see that many processes are in state R (e.g. over 50).... Strange it is that on slover machine (2*1GHz) and slover disks (7200 / 160Mb/s) this was no "strange" effect like this....
