Subject Re: Durable subscription across network connector
Date Mon, 21 Jan 2019 13:03:14 GMT
First make sure you are using the latest version of the broker.

 Second, are you using a mixture of durable subscriptions and non-durable
subscriptions? If you are you might need to add a forceDurable flag to your
set up. Normally the creation of a durable subscription by S on broker B
should create a network durable subscription for B on broker A which would
collect the messages while B is offline and then forward the messages to B
when B comes back online.  I just added some documentation for this on the
wiki but you can also see it here:
https://issues.apache.org/jira/browse/AMQ-6383
