Greetings Ed,
I recently took over a position over seeing a group of snort sensors and they've been having an issue of empty 
descriptions on some alerts.
This has been going on since before the last admin.

Just a few rules seem to generate the empty alerts yet a few of the older sensors don't have this issue.

Pulledpork version v0.6.1 is running on a non-sensor and we push the rules and the sid-msg.map files to all sensors 
from it. It's had snort version GRE (Build 71)
installed. We have a script that deploys the new rules and sid-msg.map and then restarts the snort and barnyard2 
processes on the sensors.

The 4 sensors generating the non-descriptive alerts are running a snort version GRE (Build 71) and barnyard2 
version 2.1.11 (Build 318).

The 2 sensors not having issues are running a snort version IPv6 GRE (Build 205) and barnyard2 version 2.1.9 
(Build 263).

On all the sensors the sid-msg.map is the same. The gen-msg.map files do differ but both have entries for the alerts 
that barnyard2 is picking up with no alerts.

Example alerts: Snort Alert [1:16435:0]
Snort Alert [119:32:0].

Where are you seeing those messages?
Which output plugin are you using with barnyard2?
