This may shed some light on the problem.

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).

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.
