"No matching template" shows when using multi workers.

I found these warning messages showed in the "td-agent.log" when I sent packets that only has data flowsets. The packet that has both templates and data flowsets had been sent before.

Here are some records from "td-agent.log":

I ran the Netflow plugin with 4 workers.
The numbers are the worker id printed by $log.info "#{ENV["SERVERENGINE_WORKER_ID"]}"

Is the plugin designed to work like this? (Each worker uses its own template Vash)
