FWIW I am seeing this too, except that I can still umount/remount. It appears to 
me that TCP connections to remote nfsd use a privileged source port initially, 
but if the connection is severed and reestablished later the source port is no 
longer < 1024. Client is -CURRENT, server is solaris with nfssrv:nfs_portmon=1.
