.AmqpResourceNotAvailableException: The channelMax limit is reached. Try later

I face an issue when trying to send some messages over rabbitmq protocol: The channelMax limit is reached. Try later. I'm using Spring boot rabbitmq libs and more precisely default rabbitTemplate convertAndSend method. I have to handle a lot of data in my program and need to send it over amqp.

My question is: Is rabbitTemplate creating a channel on each convertSend ? And is the channel closed after convertAndSend ?
