How to diagnose lsass.exe leaking memory on Server 2022
Jim4509 The odd thing is I have two sites, each with two DCs, and it is only one of the sites where I see this, so I need to work out what authentication activity is specific to the site where the issue manifests.
The issue follows the bulk of the authentication activity - if I reboot one the the servers, the other's rate of memory use change increases and the rebooted server's reduces, see below.

Hello, I am reviving the issue, we have a web server, server 2022, installed on 07/2024. After an update in 10/2024 (I guess so), lsass.exe started to constantly increase the memory, now it is up to 6-8gb weekly and I have to restart the server. The faulty March 2024 patch is not available on this server, so we cannot install the correct patch. I would be very happy if anyone could help on this issue. thanks.
Hello, I solved the problem and wanted to state the problem so that someone else can learn. The problem turned out to be a MailEnable IMAP service SSL problem. When I solved the problem with port 993 and SSL, lsass.exe returned to normal.
