The root page %ld of index id %d for table '%.*s' has inconsistent rootkeys information. Drop and recreate the index. Use DBCC REINDEX to rebuild indexes on system catalogs with this form of inconsistency.
This error occurs when dbcc checktable finds the root page of a btree index is not coherent with the information in sysindexes.
As noted in the message text:
If the error occurred on a user tabke, the index needs to be dropped and re-created.
If the error occurred on a system table, fix the index with dbcc reindex.
