Query breaks wp_options table

We have a site that works well most of the time. However, occasionally a query breaks the wp_options table and brings down the site. Here is the error we see when it breaks. It looks like something to do with the menu. Unfortunately the query (or maybe just the error line) is truncated so I can’t see exactly what it is trying to do. From this point we need to do a repair on the wp_options table before it will work again.

Thanks for any help!
