Ntop 3.2.1 on FreeBSD 6.0. I have another instance running on the same
box, same code that will run "forever". This instance processes WAY
more data (netflow) than the other, so must have something to do with
the number of sessions, hosts, etc. Running in gdb again so let me know
if there's something else I need to do.
Here's the args
-K -t 5 -u ntop -i none --disable-instantsessionpurge --instance
Home.Office -P
/usr/local/var/ntop -o -d -L -x 32768 -X 65536 -m
