[OpenAFS] weird problem... can't add a third DB server for pt server

I tried that, and it didn't help. 

----
All three ptservers shut down
All three sets of prdb.DB0/DBSYS1 are identical, verified with sum
All three CellServDB's are identical.

Did startup on all three ptservers
All three servers see the other ubik servers:
	Mar 16 10:46:31 srvtst02 ptserver[3484]: ubik:server 131.151.1.229
is back up: 
		will be contacted through 131.151.1.229 
	Mar 16 10:46:31 srvtst02 ptserver[3484]: ubik:server 131.151.1.228
is back up: 
		will be contacted through 131.151.1.228 
Waited 5 minutes

Pretty much all three say the same thing:

Note - if I JUST bring up srvtst02 and srvtst03, and just have those two in
the CellServDB it works just fine. It syncs up in about 20-30 seconds or so.
