MySQL Error Code 28 – No Space Left On Device

Hi,
I have a website built on WordPress with Bitnami. I am getting error thrown into my pages at heapjet.com. The error is like below:

Warning: mysqli_query(): (HY000/3): Error writing file '/opt/bitnami/mysql/tmp/MY7YPMF5' (Errcode: 28 - No space left on device) in /opt/bitnami/apps/wordpress/htdocs/wp-includes/wp-db.php on line 1924
WordPress database error: [Error writing file '/opt/bitnami/mysql/tmp/MY7YPMF5' (Errcode: 28 - No space left on device)]
SELECT t.*, tt.*, tr.object_id FROM wp_terms AS t INNER JOIN wp_term_taxonomy AS tt ON t.term_id = tt.term_id INNER JOIN wp_term_relationships AS tr ON tr.term_taxonomy_id = tt.term_taxonomy_id WHERE tt.taxonomy IN ('category', 'post_tag', 'post_format', 'language', 'post_translations', 'yst_prominent_words') AND tr.object_id IN (1724, 3629, 3643, 3651, 3675, 3677, 3684, 3692, 3702, 3708, 3718, 3722, 3727, 3770, 3780, 3792) ORDER BY t.name ASC

Can you please help me on how to solve it?

Thanks.
Arda
