Jeff,

My understanding from my own research is that for each instance of
snort on a system there needs to be an instance of barnyard2 each with
its own configuration file. Supposedly, that is all that is needed.
However, I have not been able to make it work as all but one of the
barnyards will eventually crash. Unfortunately, I have not had enough
time look for a fix, since moving to fewer systems running pf_ring
instead of a cluster of systems is a roadmap project. I will, however
be watching this thread with interest.

We run two sensors, each with 4 instances of snort and 4 instances of
barnyard2, with unique configurations for each.

Each sensor has it's own ID:

 < Sensor >      < Name > 
23      snort-campus-1:p1p1:p1p1
24      snort-campus-3:p1p1:p1p1
25      snort-campus-2:p1p1:p1p1
26      snort-campus-4:p1p1:p1p1
27      snort-dorms-1:p1p1:p1p1
28      snort-dorms-2:p1p1:p1p1
29      snort-dorms-3:p1p1:p1p1
30      snort-dorms-4:p1p1:p1p1


The "issue" generally appears at startup (and beenph indicated
sig_reference is populated at startup), with a duplicate row in
sig_reference.  All instances crash with the same error.  For example:

[jeff () snort-campus ~]$ sudo grep barn /var/log/messages|grep Duplicate

These errors have persisted even after a "delete from sig_reference;" on
the database, both before and after the InnoDB conversion.

I'm a bit loathe to recreate the database (loss of current events) but
if beenph insists that's the only sure fix, I may have to bite the bullet.
