Haamed, I have experienced this also but it's not a problem in ntop. There are two things probably happening:
1. The network load is too big for your box to handle. 2. Your TCP hash is growing to a size over 32768. You can fix the first problem by upgrading to a faster processor. I use a PIII 866Mhz with 512MB RAM and that handles that kind of network load with about 90% processor usage. The second problem is a limitation of ntop and how it deals with the number of open TCP sessions. (I think, someone please correct me if I'm wrong.) Luca has told me that he's working on a new feature that will allow it to work on larger networks.
