So you're opening a file with pcap_open_offline(), processing its packets, closing the file with pcap_close(), opening the next file with pcap_open_offline(), processing *its* packets, closing the file with pcap_close(), etc.?

Can you show us the stack trace?

...so this is probably not the best list for this - WinPcap is the port of libpcap to Windows.

tcpdump-workers at tcpdump.org is the right list for libpcap questions (and even WinPcap questions can go there if they're not asking about WinPcap-specific features).
