Hi guys, Does anyone know why would lsass.exe be using 3 GB of RAM on an application server with 8 GB of RAM in total running on Windows 2008 R2 SP1? Is this something I should log with Microsoft support? Thanks Zoran

Have you check this article. http://blogs.technet.com/b/askds/archive/2007/08/20/troubleshooting-high-lsass-cpu-utilization-on-a-domain-controller-part-1-of-2.aspx Thanks

Hi Yousuf, The server is not a DC and it's about RAM not CPU. I will try to get more info with SPA and Wireshark on Monday and will post back whatever I find. Thanks Zoran

I'm seeing the same issue on a file server, see screenshots below. All the hotfixes out there seem to be for high cpu use and not memory leaks. Did anyone else find more info on this? Thanks, techdude
