MariaDB Error 1639: Debug Sync Point Timeout
Description
This error indicates that an internal debugging synchronization point within MariaDB failed to be reached or acknowledged within a specified timeframe. It typically occurs when the server is operating with debug features enabled, often in development or testing environments, and an internal operation exceeds its expected duration for a debug-related wait. This is generally not an error encountered in production systems unless specific debug flags are inadvertently set.
Error Message
debug sync point wait timed out
Known Causes
4 known causesDebug Sync Points Enabled
The MariaDB server is configured with debug synchronization points active, which are typically used for internal testing and development.
System Resource Contention
High CPU, memory, or I/O load on the server can delay internal processes, causing debug synchronization points to time out.
Incorrect Debug Configuration
Misconfiguration of debug parameters or sync point settings can lead to unexpected timeouts during internal operations.
Internal Server State Issues
Rarely, an internal server bug, deadlock, or unexpected state could prevent a debug sync point from being reached in time.
