Well, I got error 12 for awhile again today.

WordPress database error: [Got error 12 from table handler]
SELECT DISTINCT YEAR(post_date) AS `year`, MONTH(post_date) AS `month`,
count(ID) as posts FROM wp_posts WHERE post_date < '2005-03-29 00:42:00'
AND post_status = 'publish' GROUP BY YEAR(post_date), MONTH(post_date)
ORDER BY post_date DESC

That query is made by get_archives() when retrieving by month.  It's
usually a short running query.  It simply makes a list of months.

Anyhoo, if you're curious to see what queries are made and how long they
take to run, try the attached plugin.  It dumps a list of queries into
wp_footer(), which isn't a pretty thing to put on your production blog.
Save it for a testbed.  You have to define SAVEQUERIES in wp-config for
the plugin to work (directions in the plugin).
