variables)

I'm sorry, what I actually meant was, since we don't spin up rules for
Gentoo, what OS for the Shared Object rules are you running?

Hi ;
I have used all so rules, the list below
# dynamic library rules
include $SO_RULE_PATH/bad-traffic.rules
include $SO_RULE_PATH/chat.rules
include $SO_RULE_PATH/dos.rules
include $SO_RULE_PATH/exploit.rules
include $SO_RULE_PATH/icmp.rules
include $SO_RULE_PATH/imap.rules
include $SO_RULE_PATH/misc.rules
include $SO_RULE_PATH/multimedia.rules
include $SO_RULE_PATH/netbios.rules
include $SO_RULE_PATH/nntp.rules
include $SO_RULE_PATH/p2p.rules
include $SO_RULE_PATH/smtp.rules
include $SO_RULE_PATH/sql.rules
include $SO_RULE_PATH/web-activex.rules
include $SO_RULE_PATH/web-client.rules
include $SO_RULE_PATH/web-iis.rules
include $SO_RULE_PATH/web-misc.rules
Snort is up and running normally. This issue occurs randomly.
(maybe
something triggered)

(follow up to your offlist email, yes I did receive it.)
Which SO rules are you using on gentoo?
Does Snort run for awhile and then quit? or does it quit shortly
after
startup?

Hi Again ;
Yes, my shared VRT rules are correct (2.9.0.3 also im a
subscriber)
And i
compiled them with my own parameters (because of gentoo path
difference)
then dump with my conf successfully.

Subject: Re: [Snort-users] segfault issue
We received your bug report as well. Thank you.
Are you, by chance, using Shared Object rules from the VRT? And
if
you are
using Shared Object rules, are you sure you are using the
correct
ones for
2.9.0.3?
If not, then we'll need a good backtrace of the segfault.
Check out docs/BUGS in the Snort tarball in order to get us a
core
from
Snort.
