At the risk of sounding trite, it's caused by duplicate processes trying to 
write to the database.  For example, you've started snort twice, so you 
have two processes running with the same snort.conf file and startup 
parameters.  Or you haven't specified the sensor_name in your output plugin 
configuration, you have two copies of snort running and it's defaulting to 
the same sensor_name for both processes.

In short, two things are trying to write the same *identical* information 
to the database.
