I searched the archives but didn't see any mention of this.

Since I upgraded to Snort 1.9, the alerts with the "[Xref => arachnids" 
tag are bunched together without a blank line separating them.

The alerts without the Xref tag display with whitespace between them.

SnortSnarf apparently uses the whitespace as a delimiter, so it will 
display a group of alerts bunched together as a single alert.

Has anyone else run into this problem?

My sensors are running OpenBSD 3.0.  Snort 1.9 was built from source.  
My reporting machine is running SnortSnarf-020516.1 on Solaris 8.  
Snort 1.9 was built from source.

My Snort command:
/usr/local/bin/snort -c /root/snort/snort.conf -h w.x.y.z/24 -i \
fxp1 -A full -b -D

My SnortSnarf command:
/usr/local/bin/snortsnarf.pl -d $DMZ/10/10/ -ldir \
https://reporter/dmz/2002/10/10/ -homenet w.x.y.z/24 $DMZ/10/10/alert

Thanks.
