IBM统计数据订阅主题始终返回原因2033:失败：MQRC\u NO\u MSG\u AVAILABLE

Question

我正在尝试将一些旧的java代码移植到python

我正在使用pymqi连接到队列管理器，并使用主题字符串查询所有messageflow统计主题：$SYS/Broker/+/StatisticsAccounting/Archive/#

使用现有java程序时，从主题中读取消息时不会出现问题。 当使用新的python代码时，它能够毫无问题地连接和查询主题，但总是给出消息

Reason 2033: FAILED: MQRC_NO_MSG_AVAILABLE

代理每10分钟为每个消息流发布一次Stats消息，我让新代码运行了30多分钟，从未收到消息

我也试过设置

get_opts['WaitInterval'] = pymqi.CMQC.MQWI_UNLIMITED 

坐上20分钟，而不是使用循环，但没有运气

是否有任何IIB服务器配置可能会影响我能够看到的消息，或者是否有其他选项我应该在客户端中使用
