Database Engine events and errors (18000 to 18999)

This article contains error message numbers (between the range 18,000 and 18,999) and their description, which is the text of the error message from the sys.messages catalog view. Where applicable, the error number is a link to further information.

For the full range of error numbers, see the list on Database Engine events and errors.

You can query the Database Engine to see a full list of all errors, by running the following query against the sys.messages catalog view:

SELECT message_id AS Error,
    severity AS Severity,
    [Event Logged] = CASE is_event_logged
        WHEN 0 THEN 'No' ELSE 'Yes'
        END,
    [text] AS [Description]
FROM sys.messages
WHERE language_id = 1040 /* replace 1040 with the desired language ID, such as 1033 for US English */
ORDER BY message_id;

Errors and events (18000 to 18999)

Error	Severity	Event logged	Description
18002	20	Yes	Exception happened when running extended stored procedure '%.*ls' in the library '%.*ls'. SQL Server is terminating process %d. Exception type: %ls; Exception code: 0x%lx. To generate a minidump, create an xevent session using the dump routine event with the create dump action.
18052	16	No	Error: %d, Severity: %d, State: %d.
18053	16	No	Error: %d, Severity: %d, State: %d. (Params:%ls). The error is printed in terse mode because there was error during formatting. Tracing, ETW, notifications etc are skipped.
18054	16	Yes	Error %d, severity %d, state %d was raised, but no message with that error number was found in sys.messages. If error is larger than 50000, make sure the user-defined message is added using sp_addmessage.
18055	20	Yes	Exception %d, %d occurred when the server tried to reset connection %d. Because the server cannot recover from the failure to reset the connection, the connection has been dropped. Please contact Microsoft technical support.
18056	20	Yes	The client was unable to reuse a session with SPID %d, which had been reset for connection pooling. The failure ID is %d. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message.
18057	20	Yes	Error: Failed to set up execution context.
18058	17	Yes	Failed to load format string for error %d, language id %d. Operating system error: %s. Check that the resource file matches SQL Server executable, and resource file in localized directory matches the file under English directory. Also check memory usage.
18059	16	Yes	The connection has been dropped because the principal that opened it subsequently assumed a new security context, and then tried to reset the connection under its impersonated security context. This scenario is not supported. See "Impersonation Overview" in Books Online.
18060	16	Yes	Failed to format string for error %d, language id %d. This may be caused by low memory in server, or error happening while formatting the message.
18061	20	Yes	The client was unable to join a session with SPID %d. This error may have been caused by an earlier operation failing or a change in permissions since the session was established. Check the error logs for failed operations immediately before this error message.
18100	10	Yes	Process ID %d was killed by hostname %.*ls, host process ID %d.
18113	10	Yes	SQL Server shutdown after verifying system indexes.
18124	10	Yes	The default collation was successfully changed.
18126	10	Yes	Engine failed to load configuration for error detection, default configuration was applied.

18226	10	Yes	Tape mount is being requested on drive '%s'. Expected volume has (Family ID %d, sequence %d).
18227	10	Yes	Unnamed tape (family ID %d, sequence %d, media_set_guid %s) is mounted on tape drive '%s'. This is an informational message only. No user action required.
18228	10	Yes	Tape mount request on drive '%s' is cancelled. This is an informational message only. No user action is required.

18264	10	Yes	Database backed up. Database: %s, creation date(time): %s(%s), pages dumped: %I64d, first LSN: %s, last LSN: %s, number of dump devices: %d, device information: (%s). This is an informational message only. No user action is required.
18265	10	Yes	Log was backed up. Database: %s, creation date(time): %s(%s), first LSN: %s, last LSN: %s, number of dump devices: %d, device information: (%s). This is an informational message only. No user action is required.
18266	10	Yes	Database file was backed up. Database: %s, creation date(time): %s(%s), file list: (%s), pages dumped: %I64d, number of dump devices: %d, device information: (%s). This is an informational message only. No user action is required.
18267	10	Yes	Database was restored: Database: %s, creation date(time): %s(%s), first LSN: %s, last LSN: %s, number of dump devices: %d, device information: (%s). Informational message. No user action required.
18268	10	Yes	Log was restored. Database: %s, creation date(time): %s(%s), first LSN: %s, last LSN: %s, number of dump devices: %d, device information: (%s). This is an informational message. No user action is required.
18269	10	Yes	Database file was restored. Database: %s, creation date(time): %s(%s), file list: (%s), number of dump devices: %d, device information: (%s). This is an informational message. No user action is required.
18270	10	Yes	Database differential changes were backed up. Database: %s, creation date(time): %s(%s), pages dumped: %I64d, first LSN: %s, last LSN: %s, full backup LSN: %s, number of dump devices: %d, device information: (%s). This is an informational message. No user action is required.
18271	10	Yes	Database changes were restored. Database: %s, creation date(time): %s(%s), first LSN: %s, last LSN: %s, number of dump devices: %d, device information: (%s). This is an informational message. No user action is required.
18272	16	Yes	During restore restart, an I/O error occurred on checkpoint file '%s' (operating system error %s). The statement is proceeding but cannot be restarted. Ensure that a valid storage location exists for the checkpoint file.
18273	16	Yes	Could not clear '%s' bitmap in database '%s' because of error %d. As a result, the differential or bulk-logged bitmap overstates the amount of change that will occur with the next differential or log backup. This discrepancy might slow down later differential or log backup operations and cause the backup sets to be larger than necessary. Typically, the cause of this error is insufficient resources. Investigate the failure and resolve the cause. If the error occurred on a data backup, consider taking a data backup to create a new base for future differential backups.
18274	10	Yes	Tape '%s' was dismounted from drive '%s'. This is an informational message. No user action is required.
18275	10	Yes	Unnamed tape was dismounted from drive '%s'. This is an informational message. No user action is required.

18277	10	Yes	Database file changes were restored. Database: %s, creation date(time): %s(%s), file list: (%s), number of dump devices: %d, device information: (%s). This is an informational message only. No user action is required.
18279	16	Yes	During a RESTORE operation, an I/O error occurred on checkpoint file '%s' (operating system error %s). Ensure that a valid storage location exists for the checkpoint file and try the operation again.
18280	16	Yes	The file %s is being removed from the database, but is not being removed from the filesystem because file snapshots are still associated with the file.
