Server 2022 Lsass.exe excessive memory usage

Question

Hello,

July 07/2024 installation, we have a windows server 2022 server, we use this server for web broadcasting and there are many websites, in November (11/2024) suddenly lsass.exe memory usage started to increase, so much so that web services started to stop and websites stopped working. Since then we have been looking for the problem but cannot find it and have been resetting the server every week. We are aware of the previous faulty update dated March 03/2024, but this update is not available on our server. I would appreciate it if you could help us with this. thanks.

Hello,

Here are some steps you can try:

Check for Malware: Sometimes, malware can disguise itself as lsass.exe and consume a lot of resources. Perform a full scan with reliable antivirus software to ensure your system is not infected.

Update Windows and Drivers: Ensure your Windows Server and all drivers are up to date. Sometimes, memory leaks are fixed in newer updates.

Check Third-Party Software: Some third-party security software or system services might conflict with lsass.exe. Try disabling them temporarily to see if it reduces memory usage.

Use Task Manager or Resource Monitor: Identify which processes or services are causing lsass.exe to use high memory. This can help pinpoint the root cause.

Inspect Event Viewer: Look for relevant system and application events for error messages that might be causing problems. This can provide clues about what is triggering the high memory usage.

Hello, first of all, thank you for your answer. I will do a full virus scan, can you also recommend me a command line or program where I can monitor lsass.exe? Because I can't see much detail in the task manager, if you know of a process that I can look at in more detail, I would appreciate it if you could describe it. thanks.
