Endlessly Exiting/Respawning kadmind

Question

Every 10 seconds I get the following group of messages in Console on XServe:
3/15/11 9:59:55 PM com.apple.launchd[1] (com.apple.kdcmond[999]) Exited with exit code: 1
3/15/11 9:59:55 PM com.apple.launchd[1] (com.apple.kdcmond[999]) Throttling respawn: Will start in 10 seconds
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] kadmind: Cannot bind socket.
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] bind: Address already in use
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] This probably means that another kadmind process is already
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] running, or that another program is using the server port (number 749)
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] after being assigned it by by the RFC portmap daemon. If another
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] kadmind is already running, you should kill it before
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] restarting the server. If, on the other hand, another program is
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] using the server port, you should kill it before running
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] kadmind, and ensure that the conflict does not occur in the
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] future by making sure that kadmind is started on reboot
3/15/11 10:00:00 PM edu.mit.Kerberos.kdadmin[1001] before portmap.
3/15/11 10:00:00 PM com.apple.launchd[1] (edu.mit.Kerberos.kadmind[1001]) Exited with exit code: 1
3/15/11 10:00:00 PM com.apple.launchd[1] (edu.mit.Kerberos.kadmind) Throttling respawn: Will start in 10 seconds
3/15/11 10:00:05 PM com.apple.launchd[1] (com.apple.kdcmond[1003]) posix_spawn("/usr/sbin/kdcmond", ...): No such file or directory
3/15/11 10:00:05 PM com.apple.launchd[1] (com.apple.kdcmond[1003]) Exited with code: 1
3/15/11 10:00:05 PM com.apple.launchd[1] (com.apple.kdcmond) Throttling respawn: Will start in 10 seconds
The above log entries repeat ENDLESSLY, day-in, day-out every 10 seconds!
I've tried repairing disk permissions using Disk Utility, and rebooting the server. No improvement.
I've tried killing the kadmind process using Activity Monitor, and rebooting the server. No improvement.
I searched these support forums, and found a similarly worded subject. The symptoms and steps leading up to the problem in that topic/thread seem very similar to my issue, but the solution offered doesn't tell me exactly what file to delete (and I'm not experienced enough to go deleting things willy-nilly on my server).

Any help greatly appreceated.
Running Mac OS X Server v10.6.6 on an XServe.

PROBLEM SOLVED!
Log shows that two Kerberos related processes are having issues:
1) kdcmond; and
2) kadmind.
launchd is attempting to start kdcmond, but can't find that binary/executable file. This is indicated by the line near the bottom of the error log at 10:00:05 PM: ..."/usr/sbin/kdcmond",...): No such file or directory.
launchd is also trying to start kadmind, but finding it already running/using port 749 (indicated by text in bulk of error message).
Turns out that there are some launchd files that were migrated from my v10.5 server into my v10.6 server (yes, I blame Apple for not catching this in their migration routine). The launchd files are on the server at:
/System/Library/LaunchDaemons/
The v10.5 files are:
com.apple.kdcmond.plist
edu.mit.kadmind.plist
Be sure not to confuse the second launchd file above with its v10.6 equivalent (edu.mit.Kerberos.kadmind.plist; note the "Kerberos" in the middle of the filename).
TO FIX:
1) As a precaution, I logged all Network Users out, shut down all Macs (so their would be no possibility of directory binding issues, etc.)
2) In Terminal, issue the following commands:
sudo -s
launchctl unload /System/Library/LaunchDaemons/com.apple.kdcmond.plist 2>/dev/null
launchctl unload /System/Library/LaunchDaemons/edu.mit.kadmind.plist 2>/dev/null
3) Exit Terminal.
4) Delete the two v10.5 files from /System/Library/LaunchDaemons/
com.apple.kdcmond.plist
edu.mit.kadmind.plist
5) Reboot server.
