Problem

The remote agent is dropping out due to errors similar to:

java.net.ConnectException: Connection timed out

1. Firewall/Router: Ensure that you don't have a firewall/router which might be closing network connections due to inactivity.

2. Low Network Throughput: The error can also occur, whilst sending large messages over slow network link:
   

   This problem arises because the ActiveMQ message broker continuously checks for activity on a socket, and whilst building a large message in the TCP socket buffer, the inactivity monitor will time out

As the document suggests, edit your <Bamboo_Home>/bamboo.cfg.xml file and update the section below. Set the maxInactivityDuration value to a number > 300000:

<property name="bamboo.jms.broker.client.uri">failover:(tcp://192.168.35.128:54663?wireFormat.maxInactivityDuration=300000)?maxReconnectAttempts=10&amp;initialReconnectDelay=15000</property>
