In Windows Server 2022, the phenomenon that the CPU usage rate becomes 100% rarely occurs immediately after startup.
Looking at the task manager, it consumes CPU with "system interrupt". Since mouse and keyboard operations are not accepted, a forced shutdown is performed by long-pressing the power of the server.
Investigated/confirmed
- Check the following error and warning messages in the event log
・The luafv service could not be started due to the following error. Loading of this driver is blocked
・The User Access Logging Service service hung at startup.
・TCP/IP was unable to establish an outgoing connection because the selected local endpoint was recently used to connect to the same remote endpoint.
- Device manager
From the error message in the event log, disable the device for which "!" was displayed in the item in the device manager ⇒ The event still occurs after setting
- I set the output settings of the performance monitor to output the status of the CPU, memory, and HDD at the time of occurrence as text, but the status is not output when the event occurs (Can not be output because the CPU usage rate is 100%?)
- Anti-virus software is not installed (Microsoft Defender's real-time scan is disabled)
- Check for corruption with the sfc /scannow command to investigate file system corruption. Successful completion with "No integrity violation detected".
- I have checked for hardware failures, but there are no failures
Please let me know what I can do to identify the cause.
