Bit of a confusing one here.
We are getting repeated messages in the SQL Server error log as below for a SQL Server instance:
NT AUTHORITY\SYSTEM
Reason: Failed to open the explicitly specified database XXX [CLIENT: xx.xx.xxx.xx]
SQL Server Profiler shows nothing nor does sp_who2
or sys.dm_exec_requests
.
The client IP Is actually the same SQL Server instance, with the source in the Windows Application Log being MSSQLSERVER
- so its trying to connect to itself but failing.
However I cannot find what exactly is occurring. The start of these messages is recorded in the SQL Log. As you can see the database was started up due to a CHECKDB. The CHECKDB completed then the login errors have been there since.
2015-07-13 22:11:27.790 spid30s Starting up database XXX.
2015-07-13 22:11:28.480 spid30s CHECKDB for database XXX finished without errors on 2015-07-11 03:36:12.720 (local time). This is an informational message only; no user action is required.
2015-07-13 22:11:33.780 Logon Login failed for user 'NT AUTHORITY\SYSTEM'. Reason: Failed to open the explicitly specified database XXX. [CLIENT: XX.XX.XXX.XX]
2015-07-13 22:11:38.750 Logon Login failed for user 'NT AUTHORITY\SYSTEM'. Reason: Failed to open the explicitly specified database XXX. [CLIENT: XX.XX.XXX.XX]
Any info on this would be appreciated!
