ping issues with udp? (Solaris 8)

From: topher (topher@findtopher.com)

Configuration:

Solaris 8 system with qfe0 and qfe0:1 on the same network/subnet (hostnames
'neith' and 'democritus' accordingly)

pinging the ip on qfe0 throws out a BUNCH of errors about ICMP Port
Unreachable for udp -- pinging 127.0.0.1 works just fine -- pinging
qfe0:1 works just fine... even on the qfe0 pings, the ICMP packets are getting returned... just a bunch of errors in the middle...

routing seems to be working just fine (I'm accessing the system via
ssh from a completely different VLAN/subnet) and there are no
firewalls on either the router or on the system -- nothing in
messages or syslog that seems to pertain even a LITTLE bit...

other potentially useful info:

# netstat -rn
