Chapter 10. Changes in 3.2.8

10.1. Errata

RHBA-2018:0250 – Red Hat Enterprise MRG Messaging 3.2.8 Release

BZ#1529929 - federation link heartbeat timer might not be fired on unreliable TCP connections
In previous releases, if TCP/IP connections were unreliable and packets were dropped or delayed, a TCP connection for a federation link could get stuck before the heartbeat timer started. As a result, the TCP connection could hang forever, because there was no way for brokers to know that the connection was unusable.
The heartbeat is now started when the federation link is created, thus allowing a damaged connection to be cleaned up when both sides detect that the heartbeat has timed out.
