You may get the following error when a Maintenance plan with a 'Check Database integrity' task.
Failed:(-1073548784) Executing the query "DBCC CHECKDB WITH NO_INFOMSGS
" failed with the following error: "There is insufficient system memory to run this query.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
There is insufficient system memory.
Run the DBCC CHECKDB on any of the databases on that server in Query Analyzer. See if it returns the error: 'Insufficient memory'. If so, this is a Microsoft issue and not a LiteSpeed issue.
Contact Microsoft Support for further assistance.
