Thanks.  I do not have BotHunter.  The pcap and your conf, suitably
modified, do not cause an issue on my 292.

-- Can you send the backtrace from the core file?  You will need to build
with debug enabled.

-- Can you reproduce w/o BotHunter?

-- Can you test with the latest Snort release?

Thanks
Russ

To make the email short,
Here is the output of snort running over this pcap file. (
http://sysnet.org.pk/upload/snort_issue_output.txt)
Here is the script I used to run snort (
http://sysnet.org.pk/upload/run_snort_script.txt). This is basically
"runsnort.sh" script that comes with BotHunter to run snort.

final command line this script generate is like this:-

snort-2.9.0.1-bh/src/snort -r theOne.pcap -u $_curUser -S "snort_sym_config=snort_bh_syms.conf" -c snort.curruser.conf


Here(http://sysnet.org.pk/upload/snort_bh_syms.conf) is
snort_bh_syms.conf file.
Here(http://sysnet.org.pk/upload/snort.curruser.conf) is
snort.curruser.conf.

*current scripts/outputs/configs are of snort-2.9.0.1 but I tried with
latest release of BotHunter, which contain snort-2.9.2.3 and same bug.

Regards,
Zaafar

Hi - thanks for the report.  Can you also provide your build options,
conf, and command line?

Hello,

I was running BotHunter ( latest, the one that uses "Snort 2.9.2.3 +
applied numerous stability (bug) fixes." ) and snort was crashing on my
500GB pcap file. Upon digging into the main cause, there was a dns query
that was crashing snort.

Here (http://sysnet.org.pk/upload/theOne.pcap) is the pcap file
containing only 1 packet that crashes snort. To testing this pcap, use
"115.186.147.79" as your HOME_NET. I bypassed this bug by removing this IP
from the list of HOME_NET.

Regards,
Zaafar
