Strange. Possibly due to -v1 parameter being used. Try with -v2c instead
and see if it still occurs.

http://www.squid-cache.org/Doc/config/snmp_outgoing_address/

"NOTE, snmp_incoming_address and snmp_outgoing_address can not have
        the same value since they both use port 3401."

leading to "Timeout: No Response from localhost:3401"

Solve this by removing the lines for both in and out addresses from your
config. The defaults are fine.

If you have to set the specific outgoing address for any reason, at
least make sure it is an IP assigned to the box. Not zero.

That walks the kernel. Not squid AFAIK.
