Hrm...ran ntop in gdb. No arguments. (not even daemon mode)
BTW, there is no IPv6 traffic. Thats why I didn't mention it the first
time.
(gdb) list
main.c:85: No such file or directory.

The webinterface is definitely causing problems...I've left it running for
a few minutes with no problems, but as soon as I start clicking around the

Thanks again.
