General error: 1005 Can't create table 'db_name.catalog_category_flat_store_1'

Question

I am trying to reindex Category Flat Data via ssh with the command php indexer.php --reindex catalog_category_flat but I am getting error as below. I have tried all the solutions posted on the forum but I am not able to fix the issue. Can you look into the error log and let me know if there is any way to fix the issue?

[cpanelusername@server shell]$ php indexer.php --reindex catalog_category_flat
