Cooper,

1. Can you reproduce this with every run?
2. Have you enabled the dns parser in the yaml?
3. Are event rules present in your loaded ruleset?
4. If (1) is true, can you locate the offending commit?

Possible to get a pcap(privately if you want) for this?

>> See subject.  The current dev. release of suricata has an issue where threads will get stuck at 100% cpu utilization after running for some period of time and stop processing packets.  The process then needs to terminated via 'kill -9' and restarted to free up the cores.  This does not happen in the production release.
