CHECKDB found 0 allocation errors and 7 consistency errors in database 'SolarWind_NPM'.
repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (SolarWind_NPM).". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection
not established correctly.
We repaired database with checkdb repair with data loss and no error was reported when executed dbcc checkdb. But issue was again reported in next schedule of job.
Everything is running fine from application end. Not sure what is exact issue. Need assistance !!!
Is it due to compatibility issue or its is a bug ??
