On the server running windows Server 2016, the memory of service host: local system occupies 16 GB, and the memory of svchost.exe occupies 16 GB. Why

Hello, The consumption of memory by SVCHOST service looks highly unusual, but since this is a system service to support different applications and services installed, it may be related to applications running on your system that contribute to that memory leak. Initially I would recommend to: -Run an exhaustive (Full Scan) for viruses or malware, for example using Windows Defender. This is one of the top reasons for SVCHOST memory leaks, as a malware will use and exhaust computer resources for operating. -Update your system using Windows Update, and ensure the applications installed are also updated -Run a DISM system check: https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/repair-a-windows-image?view=windows-11 -To discard 3rd Party apps causing the issue, perform a clean boot: Perform a Clean Boot: https://support.microsoft.com/en-us/topic/how-to-perform-a-clean-boot-in-windows-da2f9573-6eec-00ad-2f8a-a97a1807f3dd On the other hand, to troubleshoot deeper I can recommend the next article from Miscrosoft in order to find and troubleshoot Memory Leak issues: https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/finding-a-memory-leak --If the reply is helpful, please Upvote and Accept as answer--

You first need to identify which service is causing the problem. Right click the entry in the details tab and select "Go to service(s)". What service is it? Is there any reason for that service to use excess memory based on the workload of this machine?
