问题描述
AC后偶现传感器读值为32，门限值配置为70，但是产生了过温告警
环境信息
-
操作系统：[如 Ubuntu 24.04]
-
软件版本：[如 OpenUBMC2509]
-
硬件配置：[如 CPU、内存等]
重现步骤
-
[第一步]AC后观察系统事件
-
过温告警立马恢复
期望结果
无告警产生
实际结果
无误告警

日志如下：

通过分子日志可以看到产生告警时的读值为32，说明此时的上门限一定低于32；再看恢复时的日志可以看到，事件恢复并不是因为读值变化，而是上门限变为了70，读值低于上门限；因为上门限时配置死的，所以可以推断产生事件时读到的上门限为默认值0而非配置值
而且从传感器对象分发的事件来看，事件产生时传感器对象早已分发：
[2026-07-24 08:48:38] sensor ThresholdSensor_M2TransferCardTemp_010104 of host 0 is registered, number is 6.
求助：为什么事件对象会读到默认的上门限0，如何避免该种情况？
