> I have been testing the broker based functionality that is being added to OpenMAMA (www.openmama.org)
through use of the proton-c (0.8) and have come across an issue I have been able to reproduce
with the {{send}} / {{recv}} proton example applications.
> The issue is the the {{recv}} application is not able to receive large messages from
the send application through the Java QPID Broker, but sending the same message through the
C++ QPID Broker it works fine.
> This is reproducible as follows:  
> * Java QPID Broker is setup relatively vanilla - simply switching the authentication
to Anonymous, and adding a new topic exchange called "MAMA" (setup on Linux or Mac OS X)
> * C++ QPID Broker is built with AMQP_1 support and ran with {{--topic-patterns MAMA.*}}
(setup on Linux)
> I run the {{send}} application as follows:
> {noformat}
> ./send -a topic://10.211.55.14/MAMA/PHIL  `for i in {1..32640}; do echo -n "x" ; done`
> {noformat}
> This is just generating a large message to send.  On the receive side it is ran as follows:
> {noformat}
> ./recv topic://10.211.55.14/MAMA/PHIL
> {noformat}
> In the case when the number of characters sent is 32640 the message works fine.  If I
increase the characters to 32641 (or more) then the {{recv}} application has issues.  The
issue is different on Mac vs Linux so:
> *Mac*
> {noformat}
> Assertion failed: (msg && bytes && size), function pn_message_decode,
file /Users/ppreston/Developer/Libraries/Source/qpid-proton/proton-c/src/message/message.c,
line 656.
> Abort trap: 6
> {noformat}
> *Linux*
> {noformat}
> [0x10a3ab0]:ERROR amqp:session:invalid-field sequencing error, expected delivery-id 2,
got 1
> {noformat}
> If I run the exact same test to the C++ QPID Broker (0.32) there is no issue at all.
 Certainly with the Linux error message something is getting out of sync with large messages,
which are fragmented?
> I have attached the Java Broker Log (ran on Linux) for a run of the above where a Mac
{{recv}} and Linux {{recv}} are running, and a message is send from Linux {{send}}.
> Let me know if any extra information required.
> Thanks
> Phil
