Hi Joel

Can you explain what you mean by snort overwriting it's own memory? How
is that possible? I thought standard OS process separation would stop
that? (I am assuming you meant having >1 snort process leads to one
snort process "corrupting" another)

I also routinely run multiple snort instances - this comes as a bit of a
shock...
