> Key: QPID-7105
> URL: https://issues.apache.org/jira/browse/QPID-7105
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Environment: RH Linux
> Reporter: Alexander Moibenko

> Hello,
> I recently found that authenticated message size (GSSAPI in my case) is
> restricted to 65535.
> In cyrus-sasl there also is a restriction. According to gssapi.c it is
> 0xFFFFFF=16777215.
> In qpid SaslFactory.cpp it is hard-coded to secprops.maxbufsize = 65535;
> There are also some places where maxFrameSize is set to
> 65535. What does this mean? I know that there is a restriction on UDP
> message size, which is 64KB, but why there is a restriction to
> authenticated TCP/IP qpid message? There is not restriction to
> non-authenticated message though.
> Gordon Sim confirmed this as a bug and recommended to JIRA.
> Alexander.
> P.S. I did not indicate version, because this is in allversions
