Hi; Just to add some info, I discovered in the info.html that all packets are being queued by ntop after the first being processed. Does anyone knows why? Packets Received 1,895 Processed Immediately 1 (0.1 %) Queued 1,894 (99.9 %) Current Queue (none) 0 Maximum Queue (none) 0 (Limit 2048) Current Queue (sFlow-device.2) 1894 Maximum Queue (sFlow-device.2) 1894 (Limit 2048)

I am using sFlow plugin (no interface capture: "-i none" option) and it reports to be receiving a lot of sFlow packets, ntop receives them but only processes one packet. I tried running ntop with root user, --disable-stopcap, and other options with no luck. I did not see any problem in the ntop log, just the plugin Lastseen that fails to start with this message: LASTSEEN: Welcome to Host Last Seen.
