Description

The attached pcap shows 2 DNS requests generated by a Linux box. The first is an A, the second is an AAAA which is sent before the response to the A is received.

The result is that the requests get logged, but the responses don't due to how transactions are handled in the DNS app-layer. This will require support for overlapping transactions (or "pipelining").
