> > I've been able to isolate where the problem, but not what is the cause. From my gdb experience I kept see the Packetsourcetracker::Poll just spinning and falling through the Sweep. desc kept showing a positive value, meaning that FD_ISSET kept returning 0. I commented it out in the Poll function and new-core server started to collect packets and record networks. Unfortunately while the client connected to the server, nothing was displayed in the UI screen.

And the light bulb may have just gone off. I'll pull the latest libpcap and let you know the results. I dug deeper in the code yesterday and realized that if the select/pd_isset were not functioning then lots of stuff would stop working.

Thanks for being so patient with me.
