So, a couple of thoughts here that may point you in the right direction.

Snort, when outputting directly to DB has to stop being an IDS in order to "INSERT" into the db.  That's not generally a good thing!  

We recommend using Snort to output to unified2 and having barnyard2 input into the DB.  We are actually going to be removing the direct-to-db output from Snort in the next major release (2.9.3)
