The personal_messages table crashes often, a few times a week.
Repairs through PhpMyadmin fixes it, but not permanently.
It has been an issue for a while, and the host offers only temporary solutions.
The crashes return, and it's always "personal_messages is marked as crashed".
I've researched a bit, and the cause seems to be corruption.
The solution then is to truncate the table, export the SQL, drop the table, and then restore it.
However, I suspect there is more to it than this.
Please, do give me short pointers on what I should do and watch out for.
