> As discussed on the user mailing list
> (http://qpid.2158936.n2.nabble.com/Qpid-throwed-WSAENOBUFS-while-receiving-data-from-a-broker-td7592938.html),
> when receiving a large amounts of messages over SSL using a receiver
> prefetch, the clients fails with an exception "An operation on a socket could
> not be performed because the system lacked sufficient buffer space or because
> a queue was full". This exception seems to originate from the SslAsynchIO
> class, method sslDataIn.
> Decreasing the capacity seems to improve the frequency with which the problem
> appears. However with 1MB messages, even capacity 1 doesn't seem to work. The
> problem seems to be quite easy to reproduce using following scenario:
> 1) Create a large queue on a broker (C++ / Linux)
> 2) Start feeding messages into the queue using C++/Linux program (in my case
> I used approximately 1kB messages)
> 3) Connect with a receiver (C++/Windows) using SSL and prefetch 1000 (no
> client authentication, I used username & password)
> 4) Wait few seconds to see the error in the receiver
> The source code of the receiver as well as the full trace+ log are attached.
> Please let me know should you need some additional information.
