memory mapping

About this tag
Memory mapping in Windows refers to the technique of mapping file contents directly into a process's virtual address space, enabling efficient file I/O and shared memory. Discussions on WindowsForum.com cover practical concerns such as limiting RAM usage for memory-mapped files in applications like Elasticsearch to prevent Java garbage collection pauses. Historical threads also address critical security vulnerabilities related to memory mapping, including the Meltdown patch for Windows 7 that inadvertently allowed arbitrary memory read/write access. Additionally, a stop error (0x0000003b) has been reported when memory-mapped file usage is high in Windows 7 or Windows Server. More recently, memory mapping is relevant to AI component updates, such as KB5065504 for Phi Silica on Copilot+ PCs.

    Windows 10 Limit Memory Map files RAM usage?

    Is there any way to limit the maximum RAM that memory maps can use in Windows (for the whole os or a particular process (Elasticsearch)) so that we can keep a java application from being paged out due to lack of memory causing large garbage collection pauses?
