beenph,

Your email was about the sid-msg.map which we already have a work around 
for.

To clarify, this message is about spooler.c which is not functioning 
correctly in barnyard2-1.10.
Do you have a patch for this or work-around?

Thanks,
Larry

BTW I did send you the snort.log.xxxxx files as requested.
