[rabbitmq-discuss] Question about long-lived connections

Thu Sep 26 12:18:27 BST 2013

There is a default heartbeat negotiated between the client and the server. 
I think this is since version 3.0 but may be wrong. I guess it's value 
depends on the setup. For our Java/OSX/RHEL setup over a Gb LAN it seems to 
default to 30 minutes. We're using a load balancer in the middle though and 
this times out TCP connections after 1 minute of inactivity. We simply set 
the heartbeat to 30 seconds on the ConnectionFactory and everything stays 
alive indefinitely. Certainly many days even if there is no application 
activity.
