Subject Re: RecoveryListenerAdapter - Message id ID... could not be recovered from the data store: WAS: [Duplicate message delivered to consumers on queue with kaha persistence]
Date Mon, 08 Oct 2007 04:53:49 GMT
Hi David,

I had a test case that periodically could reproduce this - it now  
can't after ensuring references are always freshed in the Kaha  
reference store part of AMQ Store. Is your application now fixed?

thanks,

Rob
