There were changes between pre2 and the two release candidates and then the actual 3.0 release - whether those matter, I don't really recall. But we don't support pre anything, obviously.
Basically, swap usually means more hosts - and once you overfill real memory, ntop's performance sucks. It can be bad enough to not allow processes on timers to complete, backing them up, deadlocking, etc. 1. Are you using --set-pcap-nonblocking? 2. The real question is what changed in your network so that you are seeing many more hosts. The info.html and textinfo.html pages show the number of hosts... -----Burton > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of Jaco van Tonder > Sent: Monday, October 04, 2004 10:41 AM > To: [EMAIL PROTECTED] > Subject: [Ntop-dev] [FreeBSD] Ntop stuck in swread state? > > > Hi all, > > As of late (the last 2 weeks or so) I have to restart NTop every few > hours, or it crashes, with all available swap being eaten. > > If I look at top for about 2 minutes, I can actually see the amount of > swap space increasing rapidly.
