>          Components: Broker
>    Affects Versions: 5.4.2
>         Environment: Sun Solaris + JDK 1.6
> a JDBC cluster of 2 nodes running apache-activemq-5.4.2-fuse-01-00
> using MS SQL Server 2008 as a database for JDBC

> a JDBC cluster of 2 nodes running apache-activemq-5.4.2-fuse-01-00
> using MS SQL Server 2008 as a database for JDBC
> 1. 1 client (NMS STOMP , if that is any relevant) sends 10 persistent messages with TTL
set to 5 mins
> 2. after all messages have been sent and seen in the destination queue (via SQL query)
> but well before the time message are about to even start expirying
> do a 'kill -KILL' of the activemq process on node1 ("master") - so 'failover' take place

> - node2 ("slave") now becomes new "master" and resumes connections/etc
> 3. in 5 mins time all 10 messages sitting in the destination queue do expire, 
> but they do NOT end up in ActiveMQ.DLQ as they should...
> this is really bad - 
> basically the failover event breaks the promise of "guaranteed" delivery of persistent
messages
