1.
Add firewall log rules to ip(6)tables (both client and server).
To capture any nfs3 or nfs4 related errors (some traffic may be unsolicited:
error or control messages, NEW in terms of iptables)

/etc/sysconfig/iptables:
/etc/sysconfig/ip6tables:

...
# log -----------------------------------------------------------------------
-A INPUT -m limit --limit 1/second --limit-burst 5 -j LOG --log-prefix "debug"
-A FORWARD -m limit --limit 1/second --limit-burst 5 -j LOG --log-prefix "debug"
# log -----------------------------------------------------------------------

-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

2.
Restart nfs server and client (if possible).
Let them offer and obtain nfs shares.

3.
Scan /var/log/messages, also compare time stamps to those in halt debugging  
log file.
