I got index page of categories like this.

"3 Error writing file '/ramdisk/mysql/tmp/MY30mxsg' (Errcode: 28)
in:
[select p.products_image, pd.products_name, p.products_quantity, p.products_id, p.products_type, p.master_categories_id, p.manufacturers_id, p.products_price, p.products_tax_class_id, pd.products_description, IF(s.status = 1, s.specials_new_products_price, NULL) as specials_new_products_price, IF(s.status =1, s.specials_new_products_price, p.products_price) as final_price, p.products_sort_order, p.product_is_call, p.product_is_always_free_shipping, p.products_qty_box_status from zen_products_description pd, zen_products p left join zen_manufacturers m on p.manufacturers_id = m.manufacturers_id, zen_products_to_categories p2c left join zen_specials s on p2c.products_id = s.products_id where p.products_status = 1 and p.products_id = p2c.products_id and pd.products_id = p2c.products_id and pd.language_id = '1' and p2c.categories_id = '2' order by p.products_sort_order, pd.products_name]"

Also, I have uploaded Mass Products(firstly more than 60K, and then switched to less than 10K) using EP(latest version), but all uploads has gone faulty results, however, registering products are somewhat success excluding above corrupt.
I donot have good skill to manage phpMyAdmin.
