I'm even noticing it when I don't have large processes running. It's definitely not as severe, but it seems to be occurring quite regularly. As a test, I built a completely different machine with FC2. This other machine exhibited the exact same behavior. Both of these machines have 1024 MB of RAM. One is a Athlon XP 3000+ and the other is a P4 2.4 Ghz, so they aren't slow. The one thing that I haven't done is to remove LVM2 and RAID from the picture. I wonder if that would eliminate the problem? What exactly is the function of kblockd and kjournald? If anyone else has any insight, please let me know. -Brian Hanks bhanks@xxxxxxxxxx
