+There is no such 'use IPv6 only' configuration option AFAIK, this seems 
+rather like a problem. Maybe not specific to NFS, BTW.
+
+There is no --verbose flag for rpc.nfsd, but you may use rpcdebug instead:
+rpcdebug -m nfsd -s all
+
+Then, restart the nfs-server service, and check your logs.

+nfs-common service, as 90% of similar services, use an 
+/etc/sysconfig/nfs-common congiguration file. Just set NEEDIDMAPD to yes 
+to ensure it runs.
+
+Also, you'd better forget GUIs when trying to debug issue, and ressort 
+to command line instead, you'll have much more control and feedback.

+That's an interesting point, it means your actual setup differs from the 
+default package one. Try 'rpm --verify nfs-utils' and 'rpm --verify 
+nfs-utils-client' to check what has been modified exactly.

+I'm not sure what users should have to do or not, but I'm quite sure 
+this kind of imprecations won't help you solve the issue.
+
+If everything else fails, you may also inhibit IPv6 completly: just add 
+'install ipv6 /bin/true' in any file under /etc/modprobe.d, and reboot.
