Windows Server 2019 VMware虚拟机随机自动关机故障排查求助

各位大佬好，我遇到一个生产环境的棘手问题，想请大家帮忙分析下：

我有一台运行在ESXi 7.0 Update 3主机上的Windows Server虚拟机，它是生产环境里的关键数据库服务器，最近频繁出现自动关机的情况，具体细节如下：

故障现象 #

• 关机完全随机，没有固定的日期和时间，每周大概会发生2-3次
• 关机后虚拟机不会自动重启，必须手动干预开机
• 系统每次启动时会记录错误307和304，但初步排查后发现这些错误和关机原因无关

已收集的ESXi主机日志片段 #

从ESXi主机的日志里，我截取了故障发生时的关键记录，反复出现的内容如下：

其中这一行让我们倾向于是Windows系统内部发起的关机请求：

2023-01-18T19:52:26.724Z In(05) vcpu-0 - Chipset: The guest has requested that the virtual machine be powered off

已排查的内容 #

• 虚拟机的Windows许可证已正常激活
• 检查过系统电源管理设置，确认没有启用睡眠、休眠等自动关机相关的选项

现在我怀疑会不会是某次Windows更新导致的问题？想请教大家接下来应该重点排查哪些方向，或者有没有什么实用的 troubleshooting 方法？
