Re: Barnyard2 process quits when Output:alert_bro is enabled

[Jeremy Cox <jeremy.cox () washk12 org>]

There is one error in the syslog:

Jan 21 13:02:48 ids kernel: [417909.308741] barnyard2[22481]: segfault at
10 ip 0000000000423d28 sp 00007fff631c93c0 error 4 in
barnyard2[400000+46000]


Any help would be greatly appreciated!

Thanks,

Jeremy
