Error while setting up connection for rabbitmq input

Elastic Stack Logstash
1

Hi,

When I send many events to logstash I get heaps of warnings in logstash log:
All the exchanges defined in logstash config exists in rabbitmq.
It seems like a new channel is opened and closed for every event. Is this behavior necessary?

I think I can see all events in Kibana so I haven't noticed any lost events.

Can you tell what is wrong and how I can get rid of the warnings?
