Wanted to start playing more with cento, but have been running into
the following problem:

sudo /usr/local/bin/cento -i zc:<isp1> -C 100 -9 127.0.0.1:10000 -v5

It seems net flow v5 and ipfix work fine, but v9 throws the error. Any ideas?

Sorry about that. Yes, updating my version resolved the issue.
