ERROR_CACHE_PAGE_LOCKED - 752 (0x2F0)

Technical Meaning

The error code ERROR_CACHE_PAGE_LOCKED (752, 0x2F0) indicates that a cached page was locked during an operation. This typically occurs when the system attempts to modify or release a cached page that is currently in use by another process or thread.

Error Details

This error suggests that there is a conflict between the intended operation and the current state of the cached data. The cache may be holding onto a page for read operations, but it cannot be released because it is locked by another entity. This can happen in scenarios where multiple processes are accessing the same file or memory-mapped object.

Usage Context

This error code is relevant when dealing with caching mechanisms used by the operating system to improve performance. It could occur during operations such as file I/O, memory management, or any other operation that involves cached data pages.

Developer Interpretation

When encountering this error, developers should consider the following:

• Verify that all processes and threads have completed their use of the cached page before attempting to release it.
• Ensure that no other operations are currently locking the page.
• Check for any race conditions or synchronization issues that might be preventing the cache from releasing the page.

Related Errors

• ERROR_HANDLE_EOF (38): Indicates end-of-file condition, which may occur if a cached page is unexpectedly released.
• ERROR_HANDLE_DISK_FULL (145): May indicate insufficient resources to handle the operation due to disk space constraints.
• ERROR_INVALID_PARAMETER (87): Could be related if an invalid parameter was passed during the operation that led to the cache lock conflict.
