[ANSS-netops] reftek suddently stops streaming

[mwithers at memphis.edu]

Whoops, we're running cpu version 3.0.0 on the station referenced here 3.2.2
on another problem station, and 3.3.0 on still others (even the ones running
3.3.0 seem to have the problem though not as bad).  Its a little hard
to prove, but my guess is that the rt130 makes a udp connection and the
router assigns a comm port.  Then for whatever reason, the port the
router has assigned is not the same as what the rt130 and rtpd think
is being used.  Rebooting syncs everyone up again (though not today for
an unknown reason).  This gets particularly problematic with multiple
das's behind a single router.
