I've experienced this issue when I mistakenly start a second barnyard process without killing the original first. Make sure you only have 1 barnyard process running on each box Jason ________________________________ From: Jen Andre <jandre () gmail com> To: Jeff Kell <jeff-kell () utc edu> Cc: barnyard2-users () googlegroups com <barnyard2-users () googlegroups com>; snort-users () lists sourceforge net Users <snort-users () lists sourceforge net> Sent: Tue Aug 13 18:26:59 2013 Subject: Re: [Snort-users] Barnyard2 issue w/unified2 ? This is clearly a concurrency issue. You have multiple snort sensors distributed across boxes, each with their own barnyard processes -- encountering the same signature and inserting into sig_reference with the same ref_seq/sig_id combo. It will not be fixed with a different database engine. The barnyard code would need to be altered such that a) ignore on duplicate errors (not portable, see a mysql example here: https://github.com/threatstack/pigsty-mysql/blob/master/lib/pigsty-mysql/signatures.js#L170-L171) or b) retry on duplicate errors for certain tables and not crash - basically, on failure, check the db to see if a valid value exists (because another process somewhere has inserted it) and continue On Tue, Aug 13, 2013 at 2:32 PM, Jeff Kell <jeff-kell () utc edu<mailto:jeff-kell () utc edu>> wrote: On 8/9/2013 10:53 PM, beenph wrote:
I would highly suggest you that you re-create a new DB with InnoDB and restart your barnyard2 sensor.
Worked until today...
