Navigating MySQL Error 1183: Overcoming Checkpoint Issues

When managing a MySQL database, you might encounter Error 1183 – SQLSTATE: HY000 (ER_ERROR_DURING_CHECKPOINT), which indicates a problem occurred during a checkpoint operation. This error can be somewhat complex as it pertains to the internal workings of the MySQL storage engine. Let’s delve into how to understand, diagnose, and fix this error to ensure the stability and reliability of your database operations.

Understanding Error 1183

A checkpoint in MySQL is a point of synchronization between the database’s memory state and the disk state. During a checkpoint, the database ensures that all completed transactions are written to disk, and the database is brought to a consistent state. Error 1183 occurs when MySQL encounters an issue during this process.

The %d in the error message is a placeholder for a specific error number that can provide more details about the nature of the problem encountered during the checkpoint.

Diagnosing Error 1183

To diagnose this error, you’ll need to look at the MySQL error log. The error log will contain detailed information about the error, including the specific error number that replaced %d in the message. This number can give you clues about what went wrong during the checkpoint.

You can typically find the error log at one of these locations, depending on your operating system and MySQL configuration:

  • /var/log/mysql/error.log (Linux)
  • C:\ProgramData\MySQL\MySQL Server 5.7\Data\hostname.err (Windows)

Check your MySQL configuration file (my.cnf or my.ini) for the log_error directive to find the exact path to the error log.

Fixing the Error

The steps to fix Error 1183 will depend on the specific error number provided in the log and the context of the error. Here are some general strategies that can be applied:

Checking Disk Space

One common cause of checkpoint errors is insufficient disk space. Ensure that your server has enough disk space to complete the checkpoint operation:

df -h

If disk space is low, free up space by removing unnecessary files or by adding additional storage to your server.

Verifying File Permissions

MySQL must have the necessary permissions to write to the data directory and log files. Check the permissions of these directories and adjust them if necessary:

ls -ld /var/lib/mysql
ls -l /var/lib/mysql/ibdata1

Make sure the MySQL user has read and write permissions.

Checking for Disk Errors

Disk errors or corruption can also cause checkpoint failures. Use disk utility tools such as fsck on Linux or chkdsk on Windows to check and repair disk errors.

Reviewing MySQL Configuration

Improper MySQL configuration settings can also lead to checkpoint issues. Review your my.cnf or my.ini file for any configuration that might affect checkpoints, such as innodb_log_file_size or innodb_buffer_pool_size, and adjust them according to the best practices and your server’s resources.

Upgrading MySQL

If you’re running an older version of MySQL, consider upgrading to the latest stable version. Upgrades can resolve known bugs and issues that might be causing checkpoints to fail.


MySQL Error 1183 related to checkpoint operations can stem from various issues such as disk space limitations, file permissions, disk errors, or configuration problems. By methodically checking these potential causes and consulting the MySQL error log for specific error codes, you can identify and resolve the underlying problem. Regular maintenance, monitoring, and following best practices for configuration will help prevent such errors from occurring in the future.
