Hello,
linux 2.4 kernel, 486 CPU, ntop 2.1.3
The first time ntop ran (after the "real" first time to set the pass and
DBs) it ran for several hours then seg faulted on me. After that I
couldn't keep it up for more than 5 minutes. I ran it in a terminal
with -K and -t 5 and here's what happens:

Since there's a free of a NULL pointer in hash.c, I'm wondering if when
it goes to extend the hash size if it doesn't bite the dust.
Any insight/solutions would be great.
