ActiveMQ gives: "Could not connect to broker URL: tcp://localhost:61616" after around 10 000 messages

Question

ActiveMQ gives: "javax.jms.JMSException: Could not connect to broker URL: tcp://localhost:61616. Reason: java.net.BindException: Address already in use: connect" after around 10 000 messages

Then after a some time (around 1-5 seconds) start to get messages with no issue.

I'm using Spring Boot 2.0.4 with very basic configuration: spring.activemq.broker-url=tcp://localhost:61616 spring.activemq.user=admin spring.activemq.password=admin spring.activemq.packages.trust-all=true

I used JmsTemplate and now using spring integration, sadly the error is the same.

org.springframework.jms.UncategorizedJmsException: Uncategorized exception occurred during JMS processing; nested exception is javax.jms.JMSException: Could not connect to broker URL: tcp://localhost:61616. Reason: java.net.BindException: Address already in use: connect

What can cause this type of error, i dont see anything in activemq logs, but error is persistent.

Answer 1

The resolution was adding org.apache.activemq:activemq-pool and configuring the PooledConnectionFactory:

spring.activemq.pool.enabled=true spring.activemq.pool.max-connections=50

Enabling pool is not enough in Spring Boot as autoconfiguration checks for dependency.
