Fix the helper. It is sending garbage output back to Squid. Which is sometimes being treated as (wrong) responses to waiting lookups, and sometimes logged as you can see when there are no waiting lookups to corrupt. Despite the lack of wording it is an error. And a rather serious one that corrupts the security operations you are expecting the helper to perform for many transactions. > > > CentOS release 6.4 (Final) - x86_64 > Squid Cache: Version 3.5.2 > SquidGuard: 1.4 > SG is outdated software and no longer being maintained. There are some patches it needs to have applied to talk with Squid 3.4 or later. Or you can move to a helper like ufdbguard which is still maintained. Or you could move your SG rules into squid.conf, where most of them should have been to begin with. That will speed traffic up by not having to wait for helper lookups. PS. please upgrade your Squid version too. 3.5.10 is the current release and has several serious bugs and security issues fixed.
