Hello, just today I saw this kind of error on every page on my blog.

WordPress database error: [Can't create/write to file '/tmp/#sql_7719_0.MYD' (Errcode: 17)]
SELECT DISTINCT * FROM wp_posts WHERE 1=1 AND post_date_gmt <= '2006-05-03 12:54:59' AND (post_status = "publish") AND post_status != "attachment" GROUP BY wp_posts.ID ORDER BY post_date DESC LIMIT 0, 7

Then I found out that the file #sql_7719_0.MYD already exist in tmp folder. The error gone after I deleted the #sql_7719_0.MYD file.

I dont understand why the #sql_7719_0.MYD was already there, does anyone have any idea to prevent this kind of problem so it wont happen again in the future?

Thanks,
