While ihnp4 usually keeps a 3 week history of news, we had a hit on the history file on Feb. 1. This means that the 3 week "protection" against laggard duplicates on ihnp4 broke down recently. So our neighbors were left to their own history files to eliminate duplicates (typically 1 week). It appears that the net has a greater than 1 week propagation delay along certain paths, so our neighbors received duplicates (sorry). Gary Murakami AT&T Bell Laboratories ihnp4!gjm P.S. The history file may have been hit due to lack of disk space, however my current guess is that we had multiple expires running.
