Barnyard and multiple snort processes

After I reconfigured the server earlier this week I noticed that I should have way more alerts than I was getting 
within the alert file.  Here is my configuration in Barnyard -

output alert_fast: /var/log/snort/alert
output database: log, mysql, user=snort password=xxxxxxx dbname=snort host=localhost

I'm only getting alerts for 1 snort process.  I know this because when I stop the 4 snort processes and look at the 
alerts only the last one matches up with the amount of alerts I see in my database and the alert log.

Do I need to make multiple barnyard processes as well? This is for the last 5 minutes of testing:

snort[10470]:      Alerts:           41 (  0.001%)
snort[10475]:      Alerts:           59 (  0.001%)
snort[10479]:      Alerts:           66 (  0.001%)
snort[10481]:      Alerts:           62 (  0.001%)

Alert output: only 62

10614 ?        00:00:17 snort
10620 ?        00:00:10 snort
10624 ?        00:00:09 snort
10626 ?        00:00:00 snort
10483 ?        00:00:00 barnyard2
