I wonder what the timestamps are showing on the multiple copies - is 
each set n minutes apart from the previous one? For us, occasionally we 
run into this (n = 3 min when it happens). A lengthy operation - 
uploading lots of files, or sending an announcement in a site with lots 
of users - seems to cause the problem.
