1st message is just a warning. Usually happens when ntop has multiple network interfaces and is seeing the same traffic on both. But there are other causes. The (null) is a problem too.

The other messages are AFTER whatever happened - as part of the shutdown, if there is no other users, libpcap will drop promiscuous mode if it enabled it in the first place.

So what's in the log just BEFORE?  Also, try -t 5 to enable more messages.

Hello all.
I have upgraded my old version of Ntop from 3.1 to 3.2-1 and since the
upgrade Ntop stops working after a while.  Ntop stops at a random times, I
have checked the log in /var/log/messages and have come accross with loads
of RRD warnings.  I am including a sample of the warning messages as below.


        Dec  1 16:43:24 GateWay ntop[6329]:   **WARNING** RRD:
rrd_update(/usr/share/ntop/rrd/interfaces/eth0/domains/(null)/udpRcvd.  rrd)
error: illegal attempt to update using time 1164984200 when last
update time is 1164984200 (minimum one second step)

Just before Ntop stops these two messages get displayed and Ntops STOPS

        Dec  1 16:55:14 GateWay kernel: device eth1 left promiscuous mode
        Dec  1 16:55:14 GateWay kernel: device eth0 left promiscuous mode

Can some one help me with this issue as I neet Ntop running full time.

Thank you very much for your help.

Regards
Haydar
