Is the message
2013/06/02 20:15:40 kid1| assertion failed: Checklist.cc:287: "!needsAsync && !matchFinished"
in your cache.log? If so, I've encountered this as well, and have seen it with other versions of squid. I'm using this patch so squid doesn't die when this occurs, but I don't know whether this could cause other problems.
