It sounds a bit high but I can not say that it is a bug. The more hosts you will find the more memory ntop need. There are says to limit the number of hosts (by forgetting old ones) on which you can read in the documentation. > > And how much is a lot of traffic? > Several hundreds megabytes a week (let's say 600-700 MB). I have checked with upstream and this is expected behaviour. Ntop will use lot of memory because it store every host it has collected data for. Each host take a number of KB (> 8KB each) of memory. On my simple home network ntop take more than 32 MB and it has not monitored more than say 30 hosts. So if you have a high load then you need a lot of memory on that host. As upstream told. If you have a portscan on your net /24 you will be hitted with more than 16 MB in just that portscan. This is how ntop works so I will not fix this bug, more than trying to fix ntop 3.1. It has better memory handling (no resize of hashes) but it will not fix your major problem.
