WordPress MU

On my wordpress I've recently seen this error.

"WordPress database error: [Table './databasename/wp_posts' is marked as crashed and should be repaired]"

Table wp-post is shown ad "in use". So I fixed the problem by typing: REPAIR TABLE

wp_posts

But next day the same error occured. Is somebody atacking my wordpress?
(Anyone can register and write articles, althought I have to approve them before they are published).

It occured that I ran out of space at my hosting.

Sounds about right. Glad you got it working.

wp_posts?

That isn't an MU table, but glad you got it resolved.

Hmm, good catch.

if you're running regular wordpress, you need to be over at http://wordpress.org/support for assistance.
