ERROR_PAGE_FAULT_TRANSITION
A transition page fault was resolved from standby or modified state
ERROR_PAGE_FAULT_TRANSITION corresponds to Win32 error value documented as: Page fault was a transition fault. The referenced virtual page was valid in memory but not currently in the process working set, so the memory manager transitioned it back without reading ordinary file data from disk. This is usually a diagnostic memory-management status.
Where the result appears in real systems
- Kernel memory tracing.
- Performance tools classifying hard and soft faults.
- Driver debugging around locked or mapped pages.
What to collect before making changes
Record virtual address, process, access type, working-set pressure, and page-list state when available; correlate with ETW memory events rather than treating the code as an application exception.
Handling and recovery
No application recovery is normally required. Investigate only when transition faults are excessive and contribute to latency, in which case working-set policy and memory pressure are more relevant than storage errors.
What not to infer from this code
A transition fault is generally a soft fault. ERROR_PAGE_FAULT_PAGING_FILE describes a fault satisfied by secondary storage and therefore has different performance implications.
