I observed the following behaviour with the C++ broker on FC10 (with
qpidd installed via yum and also a svn co from today). If I try to
send a message with data bigger than ca. 64KB, the call to
session.messageTransfer blocks. If I disable authentication with
"--auth no",  messages of any size (tested up to 10MB) pass easily as
expected.

I used the "direct" example with a small modification to generate
messages of different sizes (e.g. for (int j=0; j<165536; j++)
message_data << "c";) to test this. With j<65495 as limit to fill
message_data, qpidd even crashes.

Is this a known/reproducible issue?

Hi Stefan,

Sorry for the delayed response.

From the trace I see you are using digest-md5 and a sasl negotiated security layer. I haven't tried digest-md5 myself yet, but it looks like you have uncovered a bug, probably somewhere in the security layer support.

I've raised a JIRA to track this:

https://issues.apache.org/jira/browse/QPID-1819
