Hi,
Suddenly I'm experiencing segfaults. This is ntop CVS on Redhat Enterprise 4. I am using Netflow. For some reason I expect a change in network configuration, but still ntop shouldn't segfault.
I collected 2 backtraces: one from ntop CVS from April 4th, and one from CVS current as of today.
Hope you can see what's wrong.
Regards, Robbert
cvs from April 4th:
