Server error log shows error WordPress database error Table

Hello All

My server error log is running into GBs and this one particular error is repeating

WordPress database error Table ‘asadm_main.wp_postmeta’ doesn’t exist for query
SELECT COUNT(meta_id)
FROM wp_postmeta
WHERE meta_key=’_menu_item_menu_item_parent’
AND meta_value=’64’
made by require(‘wp-blog-header.php’), require_once(‘wp-includes/template-loader.php’), include(‘/themes/magazine/magazine.php’), get_header, locate_template, load_template, require_once(‘/themes/magazine/header.php’), wp_nav_menu, walk_nav_menu_tree, call_user_func_array, Walker->walk, Walker->display_element, call_user_func_array, Walker_Nav_Menu->start_el, apply_filters(‘nav_menu_css_class’), call_user_func_array, astro_add_dropdown_class

Any idea on how to get it sorted?

I am using WordPress 3.9.1 running Magazine theme.
