ERROR_PAGE_FAULT_TRANSITION - 747 (0x2EB)
Page fault was a transition fault.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_PAGE_FAULT_TRANSITION error indicates a transition page fault occurred during memory access. This type of fault typically occurs when the system attempts to access a page that is not in its current state but requires it for execution or data processing.
Error Details
A page fault is an event that occurs when a process tries to access a virtual address that does not have a corresponding physical address mapping in memory. In the context of ERROR_PAGE_FAULT_TRANSITION, this indicates that the system was transitioning between different states, such as from user mode to kernel mode or vice versa.
Usage Context
This error is commonly encountered during operations involving memory management and virtual addressing. It can occur when a process attempts to access a page in a state that does not support the requested operation, leading to a transition fault.
Developer Interpretation
Developers should interpret this error as an indication that there was an attempt to access a page of memory that is currently in a transitional state. This could be due to various reasons such as incorrect memory management or invalid operations on specific types of pages.

FAQ
Q: What does a transition page fault mean?
A: A transition page fault occurs when the system is in the process of transitioning between different states and attempts to access a page that is not currently mapped.
Q: How can I troubleshoot this error?
A: Review the context of memory operations, validate parameters, and ensure correct usage of memory addresses. Check for any invalid transitions or incorrect state management.
Summary
ERROR_PAGE_FAULT_TRANSITION (0x2EB) is a specific error code indicating a transition page fault during memory access. Developers should focus on validating memory operations and ensuring proper state management to avoid such errors.
