MEMORY_MANAGEMENT

MEMORY_MANAGEMENT meaning

MEMORY_MANAGEMENT is bug check 0x0000001A. The memory manager detected a severe inconsistency. Parameter 1 identifies the subtype, and the remaining parameters describe the page, PTE, PFN entry, process, or internal structure involved.

How to analyze the result

Decode Parameter 1 before choosing tests. Inspect PTE/PFN state, page-table hierarchy, pool and MDL activity, process mappings, storage errors affecting paging, ECC or memory diagnostics, and drivers that lock or map pages.

Recovery boundary

Use the subtype and dump to separate hardware corruption from driver accounting or overwrite. Replacing RAM without subtype evidence can miss a repeatable mapping or lifetime bug.
