TigerKR, I hear you but I still don't think the problem is with the Tiger OS.

Your original note says you are running server, so I'm confused. How else are you running DNS services? And DHCP? Are you building these yourself?

You need to be totally scientific about this. I admin more than 50 Tiger/Panther clients and three servers, why haven't I had this problem? Or why haven't I seen this on the Apple mailing lists, either? If you think this is a bug that others are experiencing, too, I have found zero evidence of that.

In short, either scripting or manually restarting your server on a daily or weekly basis is a totally impractical solution, and I'm sure Apple will not figure out your problem since it doesn't sound like you're terribly clear on what the problem is, and how to fix it...

From the original hint: "Among other things, I administer two identical servers located in different locations on different LANs. They're running Mac OS X 10.4.2 client w/all updates..."

DNS is handled by Mice & Men Suite 5, and DHCPD is handled by the darwin-ports build isc-dhcpd-V3.0.2. That is the only darwin-port I have installed.

Are any of the machines that you admin Blue and White G3 towers? I don't have a problem with Tiger on any of the other computers that I administer, but they're all G4s and they aren't running DNS, DHCPD, IPFW2, nor NATD.

Just yesterday I swapped out a Blue and White tower for a Quicksilver G4 (single processor). I will try removing the daily restart on the G4 tower to see if it was a problem with the OS in relation to the old hardware.
