To prevent this error in production, your WinDev 25 code should handle disconnects gracefully. Use the HDisconnect function to ensure that when a user closes a window or the app, the server-side socket is properly released. 3. Check for Zombie Processes

Understanding the "Dump Exclusive" error in WinDev 25 is essential for maintaining stable database environments. This error typically occurs when the HFSQL engine attempts to perform a maintenance task—such as an index rebuild or a structure update—but cannot gain total control over the data files because another user or process is still connected.

In the context of WinDev, a "Dump" usually refers to the backup or export of a database structure and its data. An "Exclusive" lock means the system requires 100% of the access rights to the files. If even one client application has a .fic or .ndx file open, the HFSQL engine will throw an error because it cannot safely modify or move the files while they are in use. Common Causes of the Error
Search for any processes named WDMylocal.exe or your project’s executable name. on any lingering instances. Best Practices for WinDev 25 Database Maintenance To prevent this error in production, your WinDev
Build a "Force Close" mechanism into your app. This can be a simple timer that checks a specific record in a Param table; if you flip a "Maintenance" switch to true, the app notifies users to save and then closes itself.
