NFS locking issues: Portmapper failure

Hi,

This is a respost of
http://docs.freebsd.org/cgi/mid.cgi?20040930172241.GA2882 with some
additional information; since I got no response, I'm trying better luck
here. 

Short version: rpc.lockd does not start on a 5.3-BETA6 client
against a 4.10-p3 server, the error message is:
rpc.lockd: 100024 RPC: Port mapper failure

Everything looks ok on the server:

281,p0,0$ uname -srn
FreeBSD grummit.biaix.org 4.10-RELEASE-p3
283,p0,0$ sockstat -4 | egrep 'rpc|portmap|nfs|mount'
root     rpc.stat   114    3 udp4   *:739                 *:*

daemon   portmap    100    4 tcp4   *:111                 *:*

And from the client:

319,p0,0$ uname -srn
FreeBSD calvin.biaix.org 5.3-BETA6
320,p0,0$ rpcinfo -s grummit
   program version(s) netid(s)                         service     owner
    100000  2         udp,tcp                          portmapper  unknown
    100004  2,1       tcp,udp                          ypserv      unknown
    100005  1,3       tcp,udp                          mountd      unknown
    100003  3,2       tcp,udp                          nfs         unknown
    100021  4,3,1     tcp,udp                          nlockmgr    unknown
    100024  1         tcp,udp                          status      unknown

And I can telnet to the portmapper and nlockmgr ports from calvin to grummit
(no firewall/hosts.allow issues). I haven't been able to obtain any
debug output from rpc*, only these messages. A datapoint is that
even though I get many messages like

nfs server grummit:/fs/home/mount: not responding

whenever I start gnome, I can still do a 'ls /home'. In the ps output I
can see lots of process with "pages locked in core". I have a tcpdump
available (server-side) if anyone is interested. This is not related to
mpsafenet.

What else should I look at to try to locate the issue?
