DIRTY_NOWRITE_PAGES_CONGESTION

Dirty no-write page congestion for DIRTY_NOWRITE_PAGES_CONGESTION

DIRTY_NOWRITE_PAGES_CONGESTION is bug check code 0x000000FD.

This memory-management bug check points at dirty pages that are not eligible or able to be written back, causing the system to run out of usable memory-management options. Storage, paging, cache manager, file systems, and filters can all be involved.

How to read it in a dump

Look at dirty-page, modified-page writer, and storage stack state.
This is not simply low free RAM; the writeback path and page attributes matter.
File-system or filter drivers can keep pages dirty or unwritable.

What to check

Inspect storage errors, modified page writer state, and file-system filter drivers.
Check paging file configuration and disk health.
Use a full kernel dump because page lists and file objects are central.
