Read stops after 18 messages on queue #131
Description
Hello,
I have an ActiveMQ server running on docker. I am sending messages to queue in a for loop to experiment but after 18 messages the client stops reading the messages. What could be the reason for this?
Docker:
docker run -e ARTEMIS_USER=myUser -e ARTEMIS_PASSWORD=myPass --name mycontainer -it -p 61616:61616 -p 8161:8161 apache/activemq-artemis:latest-alpine
