freebsd stable - May 2009 - mountd doean`t start when ZFS is enabled.

I have two servers with Identical FreeBSD7.2 system. On both I have such config
in /etc/rc.conf:
rpcbind_enable="YES"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"
nfs_client_enable="YES"
nfs_server_enable="YES"
nfs_server_flags="-u -t -n 5 -h 192.168.x.y"
mountd_flags="-r"
where "x" identical for both servers and "y" is differs by
one. On one server I have ZFS storage, so
that in rc.conf I have:
zfs_enable="YES"
On server where no ZFS storage NFS server works well and mountd starts at server
startup
automatically. But on the server with ZFS storage mountd couldn`t start on
startup with such error:
mountd[855]: bindresvport_sa: Address already in use
when I correct rc.conf to:
mountd_flags="-r -p 998"
mountd begins to work.
So, is it corrct behaviour of mountd with zfs? On 7.1 anything works well, but
after cvsup and
recompilation system has falled in such troube. May be it is a bug?

Mountd can be refusing to start if there are syntax errors in those
declarations.
