Empty alert descriptions

      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].

Since the sid-msg.map file is the same, I'm thinking that there maybe a miss configuration on the 4 new sensors.

How should I go about trouble shooting this?
