WordPress Database Error: [Got error 28 from table handler]

We host approximately 500+ blogs on our servers and this evening, our servers experienced this error on ALL blogs running WordPress 2.0 – – not just one or two blogs, but all of them running the new version. On quick check – all other blogs running earlier versions did not have this issue at all, and were running fine – – so it is isolated to 2.0 users.

A quick repair of all 2.0 database tables server-wide resolved the immediate issue and the 2.0 blogs were, once again, running smoothly.

We’ve been hosting WordPress blogs for the past 2 years and never ran into this issue with any of the earlier versions of WP.

We’re just began researching this issue to make sure our client blogs aren’t interrupted by this issue again – as it just occurred on our servers approximately 10-20 minutes ago. So far, what I’ve read is that this occurs intermittently on 2.0 blogs – even after the repair of the db tables.

Any feedback would be most helpful.

Thank you!
