MySQL Error 4046: Log Flush Failure
Description
This error signifies that one or more MySQL error logging components were unable to write their buffered data to disk. It commonly occurs when the log file's path changes or its permissions are insufficient, preventing MySQL from updating its critical logs. Failure to flush logs can disrupt log rotation and hinder troubleshooting efforts.
Error Message
%d error logging component(s) failed to flush. For file-based logs this can happen when the path or permissions of the log-file have changed. Failure to flush filed-based logs may affect log-rotation.
Known Causes
4 known causesChanged Log File Path
The configured path for MySQL's log files (e.g., error log) has been altered, moved, or no longer exists, making it inaccessible for writing.
Incorrect File Permissions
The operating system permissions on the log file or its parent directory prevent the MySQL server process from writing data.
Disk Space Exhaustion
The disk partition hosting the MySQL log files has run out of available space, preventing any further write operations.
External File Lock or Corruption
Another process might have an exclusive lock on the log file, or the log file itself has become corrupted, hindering MySQL's ability to flush data.
