Everyone,

I am running Snort 1.8.1-RELEASE (Build74) on a RedHat 7.1 system,
2.4.3-12smp kernel, libpcap 0.6.2.  When I enable the stream4
pre-processor, Snort silently exits after ~ 15 minutes to several hours.  I
run snort with the following options:

     /usr/sbin/snort -u snort -g snort -e -d -D  -i eth1 -l /var/log/snort
-c /etc/snort/snort.conf

If I comment out these lines in snort.conf, it will run forever:

     #preprocessor stream4: detect_scans
     #preprocessor stream4_reassemble

Below is output from a gdb run, with a backtrace.

Thanks!
