banner problem causing error

[gabbytwin]

Hi,
For some weird unknown reason, when I go to any zencart shop that is hosted through my account this error is showing up and screwing the whole site
1 Can't create/write to file '/tmp/#sql_6a63_0.MYI' (Errcode: 28)
in:
[select banners_id, banners_title, banners_image, banners_html_text, banners_open_new_windows, banners_url from zen_banners where status = 1 and ( banners_group = 'SideBox-Banners') order by rand()]

Doesnt matter if it is a side banner or a wide banner,
I have not changed, added or done anything to the stores it is effecting,
Any ideas?
sites are
www.cheekybutts.com.au/shop
www.cheekytots.com.au/shop
www.widdlebumz.com/shop

Rang my host and he says he didnt see a problem at all??

Have checked and refreshed in both IE and firefox.
Problem wasnt there 1 hour ago?
