Error Message

4 known causesUnderlying Hardware Problems
Faulty disk drives, failing storage controllers, or memory errors can introduce silent data corruption into binary log files during writes or reads.
Operating System or Filesystem Bugs
Rare bugs within the operating system or the underlying filesystem can lead to incorrect data being written or retrieved from binary log files, resulting in logical corruption.
MariaDB Server Bugs
In rare cases, a bug within the MariaDB server itself could lead to incorrectly formatted or corrupted entries being written to the binary log.
Abnormal Server Termination
Sudden power loss or forced server shutdowns without proper MariaDB shutdown procedures can leave binary log files in an inconsistent or partially written state.
