[OpenAFS] "VL_RegisterAddrs rpc failed"

[Ty Sarna]

I recently changed some IPs on my (only) AFS server, 1.4.1 on NetBSD. 
Now FileLog contains:

Fri Jul 28 10:43:37 2006 VL_RegisterAddrs rpc failed; The IP address
exists on a different server; repair it
Fri Jul 28 10:43:37 2006 VL_RegisterAddrs rpc failed; See VLLog for details

VLLog never contains anything relevant, just:

Fri Jul 28 10:18:37 2006 Using 70.89.96.37 as my primary address
Fri Jul 28 10:18:37 2006 Starting AFS vlserver 4
(/usr/afs/libexec/openafs/vlserver)

Google turned up other cases of what sounds similar, but no concrete
advice on how to repair it.
