My Server 2003 keeps getting errors in Event log: Source: MSSQL$SQLLANSWEEPER" "SQL Server has encountered 1 occurence of cachstore flush for the 'Bound Trees' (or 'SQL Plans') cachestore (part of plan cache) due to some databse maintenance or reconfigure operations."
From the Windows 2003 server in SQL server service manager there is the SQl server, but I don't think anything else is sharing it. These errors show in the event log every few minutes.
