Microsoft has acknowledged that it rolled out a memory leak in its March patches, The Register reported Monday; however, it has fixed the issue.
For days, users were speculating about their domain controls crashing. Sysadmins were also reporting Windows Server systems freezing and restarting.
Confirming the issue, the tech giant said it is related to the “Local Security Authority Subsystem Service process on Windows Server 2012 R2 (no longer under support), 2016, 2019, and 2022”.
The problem occurs "when on-premises and cloud-based Active Directory Domain Controllers service Kerberos authentication requests," Microsoft noted in posts detailing known issues with its Server OS.
"Extreme memory leaks may cause LSASS to crash, which triggers an unscheduled reboot of underlying domain controllers," Redmond noted, adding that the root cause has been identified and a patch will be issued in coming days.
