Queue overflows after a kid restart is a known problem that I mentioned before. That is why I keep suggesting to ignore queue overflows in your environment until kid restarts are gone. There is no good reason to dig any deeper here (unless you are a Squid developer working to improve SMP queuing code). Focus on the assertions/crashes/restarts instead.
