Could be... If you read the back traffic, there are some fundamental bugs in
FreeBSD 4.x which were sometimes/partially  fixed in the later 4.x releases
but not fully until 5.2.  I wouldn't be surprised if there were other
manifestations.  You could probably check the back traffic or the cvs and
find out the FreeBSD bug report.  I don't remember the details...

There was some work-around code in 3.1 which Luca ripped out.  Without it
(or without it enabled), 3.1 (and certainly 3.2) under FreeBSD 4.x will
probably hang.

Subject: [Ntop] re: ntop crashes suddenly

ntop 3.1 / 3.2 does not run properly on FreeBSD 4.1.  I believe the problem
is FreeBSD. Ntop 3.1/3.2 works fine on FreeBSD 5.4 and FreeBSD 6.

On my FreeBSD system, I found I could run most of ntop as long as I did not
run the Summary-->Traffic link.  (This is the default page)  On that page,
ntop would trigger a Segmentation Fault generating "Historical View" graph

Every request for this RRD image URL causes a segmentation  fault:
/plugins/rrdPlugin?action=graphSummary&graphId=4&key=interfaces/bge0/&start=
now-12h&end=n


So, until we can upgrade to 5.x in the production environment, we just
bookmark this page http://localhost:3000/thptStats.html

and don't click on the Summary-->Traffic ,menu item.  Everything else seems
to work fine.
