Error 2572



Message text

Database '%S_DBID' is not in single user mode - may find spurious allocation problems due to transactions in progress.


This warning occurs when you execute dbcc checkalloc on a database that is not in single-user mode. dbcc checkalloc displays this message and then continues to execute.

Executing dbcc checkalloc on a database that is not in single-user mode may cause error messages to display that do not reflect the actual state of your database. These error messages are referred to as spurious (or false). Error messages 2521, 2540, 2546, 7939, 7940, and 7949 may be spurious under these conditions.


No action is required.
