RE: [squid-users] Why do I have "idnsCheckQueue" timeouts ?

Thanks for the reply.

Actually, the question was twofold :

1/ I cannot explain why the two squid instances do not behave identically
(one timeouts on idnsCheckQueue and not the other) when all configuration
files (squid qnd system) are the same. I checked everything by diff'ing

2/ I have effectively used a sequence
"acl INTRANET1 dst"
"acl INTRANET2 dst"
"always_direct allow INTRANET1"
"always_direct allow INTRANET2"
"never_direct allow all"
in squid.conf because I think that, coupled with "cache_peer
parent 3129 3130 default proxy-only no-netdb-exchange" will do the trick I
need : ie directly route all INTRANET1/2 requests to the servers, route all
Internet requests to the peer squid.

Your suggestions on how to achieve this more efficiently are welcome and
thanks again.

Something in your squid.conf causes Squid to try to make DNS lookups.

Possible sources:

a) http_access using dst ACL type
b) Improper forwarding setup for a DNS-less child cache
   never_direct allow all
