I installed packetbeat with the default `protocols` configuration, and my /var/log/messages immediately starts filling up with tons of errors like the following. The error asks me to report it, so here's the report.
Let me know if I can provide any other info. This is a Centos 6 machine with `packetbeat version 1.1.1 (amd64)`
