My POSTS sql table still crashes (daily if i want to...)

When i edited an old post (2007) i got these errors and had to repair the table again but i could live with that. I just don't edit my old posts anymore.
But when i edit a post that's 5 days old it now crashes.

We replaced the server a few months ago and i thought the problem was solved but still i get these crashed table errors.
Running a new version of MySQL, new Linux version (OpenSUSE) and new hardware with much more memory, faster HDD's and many more improvements.

I run several database and never have such problems with other databases but now when i edit any post on our board the message is:

- Incorrect key file for table './freesat/ubbt_POSTS.MYI'; try to repair it

Why does this keep happening?

Thanks in advance,
Rob
