I am running C++ application on Sun Solaries MQ version 5.3. C++ application is running in client mode. After running the application with purify, I am getting various uninitailized memory read error. Can anyone please tell me if I can remove these errors somehow and if this can't be removed then is it dangerous for the application ?

UMR: Uninitialized memory read:

MQCONN takes 4 parameter, out of them only one is input parameter and rest 3 are output parameters. and Input is only queue manager name that I am providing .
