qpid Java client unable to send messages

[Ashwini Mandhare <As...@symantec.com>]

Hi,

I have the C++ QPID broker component to which a Java client sends messages. I am facing certain issues with this communication and observed few errors.
I would like to get some information about like in what scenarios we get the exceptions or what is exactly causing these failures in the communication. Are following errors inter related and have same root cause?

These messages  are observed in the var/log/messages

error Could not encode string of 302 bytes as uint8_t string. (qpid/framing/Buffer.cpp:255)

error framing-error: Framing version unsupported (qpid/framing/AMQFrame.cpp:93)

At the java client we are getting following exceptions

org.apache.qpid.AMQException: timed out waiting for sync: complete = 91, point = 101 [error code 541: internal error]
javax.jms.IllegalStateException: Object org.apache.qpid.client.AMQSession_0_10@25c1c64c has been closed

Could you please help us identify the cause for this exceptions and share the information.

Thanks and Regards,
