Try debug_options ALL,1 15,6 and look for /neighborsUdpPing/ in your
cache.log. (WARNING: This could make your cache.log grow very large
in a short time) There you can see if source_ping is used or not. If
it is used then your neighbor/parent-caches are faster than your

(Have you installed the pinger-program as root?!)

Squid gets the object from a parent which has to fetch it itself.
The TIMEOUT_ shows that not all icp-requests to your
parents/neighbors were coming back in the neighbor_timeout -time
(default 2sec)

See above, and see your configuration, especially inside_firewall
(all which isn't in this will be fetched through neighbors and
parents) and local_domain (all in this goes direct)
