This isn't an upgrade of FBSD 4.x or 5.x, is it? Or an upgrade of an
older version of ntop? The reason I ask is that this was a problem that
was noted in ntop 2.something under 4.x and 5.x. If you google for the
specific error message:

http://www.google.com/search?hl=en&lr=&q=ntop+freebsd+%22gzflush+error%22&btnG=Search

you'll see stuff like that talked about in several places.

I just flattened the box when I upgraded the OS, starting from a fresh
install of 6.0, then cvsupping the ports to get ntop current, and all
has been well since.
