Upgrading the 2nd gateway did indeed fix the problem of the weird default 
route.  We're still seeing a lot of hslsd core dumps though (running CUWiN 
r3715 and the 8-Dec netbsd snapshot).  From the timestamps (and adjusting 
for the watchdog timeout), they happen anywhere from immediately after 
hslsd is restarted to 90 minutes later, with the mean at about 22 minutes.

I put the latest core files with the output from 'mkstaboot -S -S' here, 
if they can tell you anything:
