423
Client Error
423 Locked
The resource that is being accessed is locked (WebDAV).
Description
423 Locked is a WebDAV status code (RFC 4918) indicating that the source or destination resource of a method is locked. This prevents concurrent modifications to the same resource by multiple users.
In modern APIs, it may be used to indicate that a resource is temporarily locked due to an ongoing operation (e.g. file being processed, record being edited by another user).
Common Causes
- WebDAV file locked for exclusive write access by another user
- Database record locked during a transaction
- File being processed (video encoding, report generation)
- Distributed system lock held by another node
How to Fix
- Wait and retry with exponential backoff
- Check for a
Lock-Tokenheader to identify the lock holder - Implement lock timeouts to prevent indefinite locks
- Show the user a "resource is being edited by [user]" message
