Hi Burton, I've added a patch to ntop for the problem below. I'm currently testing the patch so I will let you know later this week.
My feeling is that the Linux memory management (expecially in the latest releases) is somehow broken. I have noticed for instance that in the latest RH 7.3 ntop does not always complete the shutdown (a call to free() loops forever). This didn't happen on 7.2 AFAIK. ntop on Solaris with the very same traffic runs beautifully. Any clue? Cheers, Luca ----- Original Message ----- From: "Burton M.
