I see.... Sometimes I see log events related idle sessions and shortly after ntop dies. Perhaps some of my instability is related to this issue as well? Maybe it's time for me to do some more detailed investigation.

Unfortunately the size of the DNS database is small, so I will keep on digging cause I have the same problem on multiple machines. -rw-r----- 1 root ntop 2367653 Feb 7 13:38 /usr/local/var/ntop/dnsCache.db Regards, Radu ======================== Date: Thu, 7 Feb 2008 11:22:25 -0600 From: "Gary Gatten" <[EMAIL PROTECTED]> Subject: Re: [Ntop] Ntop 3.3 on FC4 or FC5 will crash after a while (10min to XXdays) To: <[email protected]> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset="us-ascii" Don't know if it will help in your case, but the dnsCache.db file seems to cause me trouble when it gets "big". Stop nTop, delete that file, and fire it up again. Maybe it will help - if not you didn't really hurt anything.
