As a followup, I've determined that it is network related, but I'm still not sure what the problem is. I did go back to CentOS 5.2, but the problem still exists with that version, too.
Basically, what seems to be happening is that the network freezes around 30 seconds, and then picks right back up. There are no errors in any logs that I can find, and process that are running locally and that only depend on local resources keep right on going and don't have a problem.
I have tried using a different network card (as opposed to the one on the motherboard), but the problem happens with that, too. It almost has to be a configuration issue, or a BIOS settting, but I don't get it.
Some kind of power saving "feature" or wake on lan...?
