Subject Slow sending of messages
Date Fri, 18 Dec 2009 21:28:41 GMT

Hello All

On 5.3.0.4 and 5.3.0.5

Seeing some odd behaviour with a messageproducer.send
Sometimes it takes a very long time. ranging from < 10 milliseconds to > 60
seconds!

I have all persistence turned off, flow control off and can't see any reason
for it. 

Running a standalone broker with a separate machine sending via it. In the
debug logs on the broker I see these messages:

What is the pagedInMessages referring to and could I be hitting 
http://issues.apache.org/activemq/browse/AMQ-2413
issues?

Any other ideas? I have fast consumers and producers but I just can't find
any reference to what the pagedinmessages are referring to.

Any help would be really appreciated as this is totally confusing me :-(

many thanks

Adrian
