I am having similar trouble with 5.1.  For me, rpc.lockd is eating up 
all my low (privileged) udp ports.  You can tell the system to use a 
different range for low ports.  Use the sysctl command and tweak the 
net.inet.ip.portrange.lowlast variable.  By default, it sets the 
lower bound for privileged ports to 600.  You might increase it past 
631 to ensure that no process snatches it up.  Of course, you would 
have fewer privileged ports, which might create problems on a busy 
machine running NIS (which is the situtation that brought this 
problem to my attention).
