Presumably, if you're using that code, it's only calling pcap_findalldevs_ex() once, so it's not a *continuing* leak, however.<br>

I wanted to see what was causing the memory usage, and my first notion was that packets weren't getting freed somewhere. So I swapped out my packet_handler() function for the example one which comes in basic_dump.c, and switched my libraries to 4.1.1.<br>

<br></div>How do you know that it's WinPcap, not your application? WinPcap isn't supposed to keep allocating memory while you're capturing traffic, no matter *how* it's configured.<br><br>Could you send us your code, so we can see whether there's a leak in it?<br>
