What does a history of - imply about a connection in conn.log? I have a significant number of conn events with that for a history, and I am wondering if this is possibly because of duplicate packets. Thanks! ---

I'm not sure off hand. I checked some code and can't quite explain it. Can you send me some of your conn log entries off list where you are seeing this? I wonder if there are any other clues in the log.   .Seth ---
