What Are the Top 25 Most Common SQL Server Engine Errors? (MSSQLSERVER_XXXX)
The SQL Server engine is an incredibly complex system that can sometimes cause unexpected errors. Despite its robustness, the engine can still encounter issues. In this post, we will look at the 25 most common SQL Server engine errors and how to address them.

1. MSSQLSERVER_17187
MSSQLSERVER_17187 occurs when the SQL Server engine is unable to read the data file due to a hardware failure or corruption of the file. To resolve this error, you must replace the corrupted file or repair the hardware.

2. MSSQLSERVER_17054
MSSQLSERVER_17054 occurs when the SQL Server engine attempts to start but fails due to insufficient memory. To resolve this issue, you must add more memory to the system or free up memory by closing unnecessary programs or services.

3. MSSQLSERVER_17113
MSSQLSERVER_17113 occurs when SQL Server fails to start due to a missing or corrupt master database file. To resolve this issue, you must either recover the corrupt file or restore the missing file from a backup.

4. MSSQLSERVER_18456
MSSQLSERVER_18456 occurs when a user attempts to log in to the SQL Server engine but the authentication fails. To resolve this issue, you must ensure the user has the correct permissions and the password is correct.

5. MSSQLSERVER_18452
MSSQLSERVER_18452 occurs when a user attempts to log in to the SQL Server engine but the authentication fails due to an expired password. To resolve this issue, you must ensure the user has the correct permissions and reset the password.

6. MSSQLSERVER_17204
MSSQLSERVER_17204 occurs when the SQL Server engine fails to start due to a failure to open the error log file. To resolve this issue, you must check the permissions on the error log file and ensure the file is not corrupted or missing.

7. MSSQLSERVER_17207
MSSQLSERVER_17207 occurs when the SQL Server engine fails to start due to an invalid security certificate. To resolve this issue, you must ensure the certificate is valid and the correct permissions are assigned.

8. MSSQLSERVER_17220
MSSQLSERVER_17220 occurs when the SQL Server engine fails to start due to a missing or corrupt master database. To resolve this issue, you must either recover the corrupt file or restore the missing file from a backup.

9. MSSQLSERVER_17222
MSSQLSERVER_17222 occurs when the SQL Server engine fails to start due to an invalid configuration option. To resolve this issue, you must identify and correct the invalid configuration option.

10. MSSQLSERVER_17066
MSSQLSERVER_17066 occurs when the SQL Server engine fails to start due to a missing or corrupt transaction log file. To resolve this issue, you must either recover the corrupt file or restore the missing file from a backup.

How to Prevent SQL Server Engine Errors
SQL Server engine errors can be disruptive and cause downtime, which can have a negative impact on your business. As such, it is important to take proactive steps to avoid and prevent these errors. Here are some tips on how to do this:

1. Perform Regular Backups
Regular backups are essential for disaster recovery. By performing backups on a regular basis, you can restore corrupted or missing data files and transaction logs, which can help to prevent and avoid SQL Server engine errors.

2. Monitor SQL Server Activity
Monitoring SQL Server activity is essential for identifying potential issues before they become critical errors. By monitoring the system, you can detect any errors at an early stage and address them before they become serious.

3. Keep SQL Server Updated
Keeping the SQL Server engine up-to-date is essential for avoiding errors. Microsoft regularly releases updates and patches to address known issues and security vulnerabilities. Make sure to install the latest updates and patches as soon as they are released.

4. Monitor Hardware
Hardware failures can cause SQL Server engine errors. To prevent these errors, you must monitor the hardware on a regular basis and replace any components that are failing or showing signs of wear and tear.

Conclusion
SQL Server engine errors can be disruptive and cause downtime. By taking proactive steps such as performing regular backups, monitoring SQL Server activity, keeping the engine up-to-date, and monitoring hardware, you can reduce the risk of experiencing these errors.
