Help! Errcode

[theladebug]

My site has been working fine up until today.

I noticed that my host (doteasy) made some changes to their site admin panel and I dont know if they are related...

Basically on my home page I am getting:
1 Can't create/write to file '/var/lib/mysql/#sql_c18_0.MYI' (Errcode: 13)
in:
[select banners_id, banners_title, banners_image, banners_html_text, banners_open_new_windows, banners_url from banners where status = 1 and ( banners_group = 'Wide-Banners') order by rand()]

and then in my categories I'm seeing:

1 Can't create/write to file '/var/lib/mysql/#sql_c18_0.MYI' (Errcode: 13)
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 products_description pd, products p left join manufacturers m on p.manufacturers_id = m.manufacturers_id, products_to_categories p2c left join 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 = '1' order by p.products_sort_order, pd.products_name]

Does anyone have any idea what I can try?
