Hi Herbert, I would like to clarify that the latest version of legacy JMS client for AMQP 0-x is 6.4.0. You can find more details on this old JMS client at: http://qpid.apache.org/components/jms/amqp-0-x.html http://qpid.apache.org/releases/qpid-jms-amqp-0-x-6.4.0/ Kind Regards, Alex On Fri, 12

Dispatch Router: Wow. Large message test with different buffer sizes

Well, *this* certainly made a difference! I tried this test: *message size:* 20 bytes *client-pairs:* 10 *sender pause between messages:* 10 msec *messages per sender:* 10,000 * credit window:* 1000 *Results:*

Re: [RABBITMQ/QPID-JMS/VHOST] failed to connect to a virtual host

So, the Qpid JMS client only speaks AMQP 1.0. In the past we released a different JMS client which spoke AMQP 0-9-1, and AMQP 0-10. I believe that last release of that is detailed here: https://qpid.apache.org/releases/qpid-java-6.1.7/index.html Just to forewarn - I believe there are a few issue

Re: Dispatch Router: Changing buffer size in buffer.c blows up AMQP.

*A better test would involve much larger messages, maybe 64K, 128K, or more.* Oh I see -- OK, that will be easy. This is something that needs to be fixed though, I expect. On Fri, Feb 12, 2021 at 12:08 PM Michael Goulish wrote: > A further note. > I just looked at all 100 receivers this way. >

Re: Dispatch Router: Changing buffer size in buffer.c blows up AMQP.

A further note. I just looked at all 100 receivers this way. They all have the same inflection point at 28000 messages. But ... it could also have been a particular point in time that triggered it -- because the all hit the 28000 message mark within 2.5 seconds of each other. On Fri, Feb 12, 2021

Re: Dispatch Router: Changing buffer size in buffer.c blows up AMQP.

Another thing to consider when increasing the buffer size is how to adjust the "Q2" limit. This limits the number of buffers that will be stored in a streaming message at any one time. By increasing the buffer size by 8x, the Q2 limit in bytes is also increased 8x. This won't have any effect on

RE: [RABBITMQ/QPID-JMS/VHOST] failed to connect to a virtual host

Got your point. If I understand this well, if I force QPID to use AMQP 0-9-1 than it might work. Am I assuming well :-) Is there a way to have QPID explicitly use AMQP 0-9-1 ? Or do I need to downgrade QPID's version ? (By the way, your help is much appreciated ;-) ) -Message d'origine

Re: [RABBITMQ/QPID-JMS/VHOST] failed to connect to a virtual host

So, I think what you are seeing here is essentially a bug in the RabbtMQ AMQP 1.0 plugin. IIRC (and it's been a while) they incorrectly assume an equivalence between the notion of terminus durability in AMQP 1.0 and Queue durability in AMQP 0-9-1. The log message you see: 2021-02-12 14:50:48.451
