When an unexpected error is received during communication between apd, apmd, and mcpd, it throws an exception.


The system cores without an error code indicating the reason. This hampers finding the actual cause for the error.


Rarely reproducible, failed communication between apd, apmd, and mcpd.



Fix Information

Now, when an error occurs, the system prints an error code in HEX, which facilitates finding the reason for the error.
