Microsoft’s Windows Server 2025 memory-management change is causing application crashes and SQL Server instability on affected systems. The problem hits software that uses Address Windowing Extensions (AWE), including deployments with Lock Pages in Memory (LPIM) enabled. Impacted servers can show memory corruption, 0xC0000005 access violations, failed DBCC CHECKDB jobs, and services that stop or restart unexpectedly. Microsoft has issued a temporary workaround and says a future Windows update will provide a permanent fix.
