I think I didn't get a debug log that shows this problem. At least I have none in my mail archive. In any case, in order to track this down quickly, I need a debug log where the vast majority of traffic is from a system that doesn't appear to be right. So that I can see which receive is from that system and how it is processed. It is much harder to try to analyze this is there are several hosts and I don't know what to look at. Note that I am off to the Fedora Developer Conference tomorrow and busy there for the rest of the week.
