Microsoft has mounted a bug that was inflicting some Home windows Server 2022 methods with two or extra NUMA nodes to fail to start out up.
NUMA (brief for non-uniform reminiscence entry) is a pc reminiscence structure through which a number of processors are related to the identical shared reminiscence pool by way of high-speed interconnections to manage efficiency bottlenecks.
This design is extensively utilized in Home windows servers with a number of bodily central processing items (CPUs) or multi-core processors, that are widespread in enterprise computing and different industries requiring high-performance computing (HPC).
A Home windows Server NUMA node optimizes how CPUs and reminiscence work together to enhance efficiency and enhance velocity in multi-processor methods. It offers sooner entry to “local” reminiscence for particular processors, which might take longer when connecting to “remote” (farther away) reminiscence linked to different nodes.
“Some servers that have two or more NUMA nodes fail to start up,” Microsoft defined within the KB5052819 help doc revealed over the weekend.
“If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.”
The corporate additionally launched the Home windows Server 2022 servicing stack replace (KB5050117), which incorporates high quality enhancements to the servicing stack, the Home windows part that installs updates.
“Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates,” Redmond defined.
In September, Microsoft mounted one other identified problem inflicting Home windows Server 2019 boot issues, freezes, and efficiency points after putting in the August 2024 safety updates.
Two months later, it addressed a number of bugs that precipitated set up, improve, and Blue Display of Demise (BSOD) points on Home windows Server 2025 gadgets with a excessive core rely.
Microsoft can also be engaged on a repair for one more Home windows Server 2025 problem that causes boot issues on methods in iSCSI environments to fail besides and show “boot device inaccessible” errors.
