当消息流向V 7版本之前的队列管理器时，除了那些在消息描述符中的属性之外，消息属性都被看作是消息数据并计入消息长度中。
When a message flows to a queue manager prior to V7, properties of the message, except those in the message descriptor, are treated as message data and count towards the length of the message.
它所预期处理的消息量是每天1,000,000条消息(后文将讨论峰值速率)，消息平均大小为3.5K(含消息描述符——MQMD)。
Its anticipated message volume is 1,000,000 messages per day (peak rates are discussed later), with an average message size of 3.5k including the message descriptor (MQMD).
在这种情况下不需要输出错误消息，因为文件描述符0到2只是在攻击者试图去搅乱您的程序的时候才会被关闭。
There's no need to print error messages for this case since file descriptors 0 through 2 are only closed if an attacker is trying to subvert your program.
