I'm aware there's a memory problem when NetFlow is used. I'm tracking it. Stay tuned.
Cheers, Luca

Hi,
I am using the latest CVS ntop, on a Suse 9.1 box, 2x3.0Ghz Xeon + 1.5GB RAM, and it will run for varying amounts of time (so far the record is ~ 9 hours) before crashing.

It is lasting this much because I enabled --track-local-hosts and disabled DNS, otherwise it would be crashing within several minutes. I am receiving 5 NetFlows, and as of now there are 271 active end nodes.
CPU utilization never goes above 3%, and with --track-local-hosts, the highest memory utilization was around 50% before it died.
What can I do to stop it from going down, and possibly even disable --track-local-hosts so I can see where connections are ending ?
Thanks,
Stefan.
