Hello there.
The last snapshot for ntop insists on signaling a segmentation fault after
some minutes. It faults alone, without any intervention from the browser.
The machine is a RedHat Linux 6.2, libcap 0.7.1.
The command line is set args -w 4000 -u nobody -P /var/log/ntop -a
/var/log/ntop/ntop.log -K
I've started it with gdb, and the traceback shows the following information:
10/May/2002 11:22:45 Started thread (6151) for network packet sniffing on
eth0.

The session that is being freed exists, and the pointer seems to be valid,
but there is a problem somewhere that breaks the free of the memory. I
haven't seen an excessive
Hope this helps in fix these memory problems.
