If there is a 'useful' artificat in the journal which is 'tied' to a message on the DLQ, that means the journal can't be cleared, right? The only way to clear the journal is to delete the message from the DLQ first, correct?

So you might need to post your config (or show the code for your config if embedded). "Memory Limits" set to 320MB isn't the same thing as "Store Limits" set to 320MB with 32MB journal files. Individual files will be cleared out if there are no useful artifacts in them (messages, durable subscription info, producer audit data structures, etc...). The default cleanup period is 30s: eg: <kahaDB cleanupInterval="30000" ..> >This 1 message blocks the freeing up of the journal file where it resides. In >order to resolve this, the JVM is >recycled. I'm sure there is a better way >of resolving this issue. Any advice? Are producer/consumer using same connection? What ack mode is your consumer using? Since this is embedded (broker,producer,consumer) it should be easy enough to extract out the salient points and put together a unit test. If you provide something concrete like that, I can take a look and tell you exactly what's happening. > > Regards, > > Barry Barnett > WMQ Enterprise Services & Solutions > Wells Fargo > Cell: 704-564-5501 > > > -- Christian Posta http://www.christianposta.com/blog twitter: @christianposta
