SpringBoot3.0.5升级后MQRC_UNKNOWN_OBJECT_NAME异常致MQ连接数持续增长问题

• 触发场景：当抛出MQRC_UNKNOWN_OBJECT_NAME（2085）异常时，应用到MQ Channel的连接数持续增长
• 稳定条件：仅在服务器上创建对应缺失队列后，连接数才会保持稳定；否则每触发一次异常，连接数就同步增加
• 版本关联：该问题在升级SpringBoot至3.0.5并替换为Jakarta相关库后出现，此前的Spring/JMS版本无此问题

连接数查看命令及输出 #

echo " dis chs(MQCHANNEL.SVRCONN)" | runmqsc | grep CONNAME | sort | uniq -c

    180    CONNAME(1.128.4.11)                     CURRENT
