Question

I wrote a query and this runs on my local server correctly it has less data,

but when i run this on production server it gets an error – (this has more data around 6GB)

Incorrect key file for table '/tmp/#sql_3c51_0.MYI'; try to repair it

Here is my query

SELECT   
    `j25_virtuemart_products`.`virtuemart_product_id`,
    `product_name`, 
    `product_unit`,
    `product_s_desc`,
    `file_url_thumb`,
    `virtuemart_custom_id`, 
    `custom_value`   
    FROM 
    `j25_virtuemart_product_customfields`,
    `j25_virtuemart_products`,
    `j25_virtuemart_products_en_gb`,
    `j25_virtuemart_product_medias`,
    `j25_virtuemart_medias`     
    WHERE
    (
    `j25_virtuemart_products`.`virtuemart_product_id`=`j25_virtuemart_products_en_gb`.`virtuemart_product_id`
    AND 
    `j25_virtuemart_products`.`virtuemart_product_id`=`j25_virtuemart_product_customfields`.`virtuemart_product_id`)

AND

    `j25_virtuemart_products`.`virtuemart_product_id`=`j25_virtuemart_product_medias`.`virtuemart_product_id`
    AND 
    `j25_virtuemart_product_medias`.`virtuemart_media_id`=`j25_virtuemart_medias`.`virtuemart_media_id`

    GROUP BY `j25_virtuemart_products`.`virtuemart_product_id`

    LIMIT 0, 1000;

Anyone know how to recover from that error – something like otimize this query or any other way
thank you
