To get back to the more obvious:
Are you sharing the connection among all threads, or are you using a connection per thread? As you are listening for messages on the queue, you should really be using a connection per thread. Makes cleaning up a thread operation...

Seems to me like you might have been trying to read from a queue while a different thread had closed the connection, maybe after some exception?

Hi Bob,
I changed my c++ application to use MQCTL/MQCB... But my MQCB returns with 2012. MQRC_ENVIRONMENT_ERROR. From documentation i understood that its related to not being able to create posix threads from my application. Is there anything i need to do on linux to allow posix threads for c++ applications?


Enabling posix threads in C++ requires changing your thread generation to use pthread.h and including a posix threading library. Depending on your compiler, this may or may not be possible.
