[squid-users] external ACL queue overload

[Vieri]

Hi,

I sometimes get messages such as this one:

WARNING: external ACL 'bllookup' queue overload. Using stale result.

My squid.conf has this defined:

external_acl_type bllookup ttl=60 %URI /opt/custom/scripts/run/scripts/firewall/squid_url_lookup.pl -tbl_name=shallalist_bl adv,aggressive,...

Does it make sense to increase the following values:

ttl=86400 children-max=50 children-startup=2 children-idle=5

I'd like to know what "children-startup" means exactly.

Thanks,

Vieri
