Martin Serrano commented on AMQ-3542:
-------------------------------------
note: Make sure you do not have randomize=false on your failover uri as I did.
I copied it from a place where that makes sense. In this situation, it means
the {{a}} part of the failover would always be chosen when recovery occurs and
it will never fail over. That was a wasted day.
> Using failover: with static discovery in a network connector to choose from a
> master/slave tuple leads to hangs and invalid states

> Key: AMQ-3542
> URL: https://issues.apache.org/jira/browse/AMQ-3542
> Project: ActiveMQ
> Issue Type: Bug
> Components: Connector, Transport
> Affects Versions: 5.4.2, 5.5.0
> Reporter: Gary Tully
> Assignee: Gary Tully
> Labels: failover, master, network, slave
> Fix For: 5.6.0

>
> static discovery will try to connect to all provided urls. When the list is a
> master/slave pair with shared storage, only one will active, leading log
> messages indicating repeated failure to connect.
> A potential solution is to use failover: just to pick a url but let it
> delegate failover to the network connector such that the network bridge is
> correctly stopped/restarted.
>
> {{static:(failover:(tcp://a:61616,tcp://slave:61616)?maxReconnectAttempts=..)}}
> This does not work reliably atm, due to inconsistency in the failover
> reconnect logic, a network connectors interest in transport
> interruption/resumption and the lack of thread safety in tracking existing
> bridges.
