This probably means that the port is opened by an NFS-related kernel thread
because portmap (incorrectly) assigns the port there.  You can confirm this
by stopping the NFS server (/etc/init.d/nfs-kernel-server and
/etc/init.d/nfs-common) and starting cupsys again.

This is not a bug in cupsys, but a systemic problem with portmap's random
port assignment process.
