Gary- not DNS cache. Look at Radu's backtrace: FC4 crash *** glibc detected *** ntop: free(): invalid pointer: 0x089681f0 *** ======= Backtrace: ========= /lib/libc.so.6[0xe511e0] /lib/libc.so.6(__libc_free+0x77)[0xe5172b] /usr/local/lib/libntopreport-3.3(ntop_safefree+0x27)[0x7c082b] /usr/local/lib/libntopreport-3.3(freeSession+0x124)[0x7d63f0] /usr/local/lib/libntopreport-3.3(scanTimedoutTCPSessions+0x1dc)[0x7d699c] /usr/local/lib/libntopreport-3.3(purgeIdleHosts+0x3bb)[0x7ba08f] /usr/local/lib/libntopreport-3.3(scanIdleLoop+0x22f)[0x7c16e3] /lib/libpthread.so.0[0x6fcbd4] /lib/libc.so.6(__clone+0x5e)[0xeb84fe] ======= Memory map: ========
It's running the idle scan and freeing a session. That's some kind of internal corruption, not dns cache... -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Radu Constantinescu Sent: Thursday, February 07, 2008 12:44 PM To: [email protected] Subject: Re: [Ntop] Ntop 3.3 on FC4 or FC5 will crash after a while Gary, Thanks for the idea. 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.
