The problem seems to be releated to the number of hosts? I'm assuming
this because the following info show hash.c to be a problem.
Any ideas on how to fix? I'm going to try the CVS dated 9-9-02 in the
next day or two.

1. The web page version of ntop seems to lockup after running for a
while. I think it is still
processing items because the browser will continue to spin (not give a
refused connection message).
2. /usr/local/bin/ntop -P/home/ntop -untop -d -M -K
-ieth0,eth1,eth2,eth3 -wxxx.xxx.xxx.xxx:3000 -L -S 1
The xxx.xxx.xxx.xxx is the IP address of eth0

4. Compaq deskpro pentium2 350 single processor with 392 megs ram
4 network cards SMC 10/100 monitoring 3 interfaces 1 interface is
for web server
5. All interfaces are public
All interfaces are 100 meg (eth1,eth2 have 10 meg bandwidth limit)
roughly a couple thousand computers (estimate). I do no filitering
so anyone who connects to campus will show-up.
