Hello,

I am experiencing an error on decoding messages from a Cisco ASR 1k.

Graylog version is Graylog v2.3.1+9f2c6ef, and Netflow Plugin is 2.3.0-rc.5.

Attached is the PCAP file for the messages.

Following is the error message:

2017-10-05T13:19:17.396-03:00 ERROR [DecodingProcessor] Unable to decode raw message RawMessage{id=ef8299f0-a9e8-11e7-aa1d-001a4a160183, journalOffset=68844, codec=netflow, payloadSize=102, timestamp=2017-10-05T16:19:17.391Z, remoteAddress=/172.30.30.51:54375} on input <59d5a3075c9eef39fabd64d0>.
