wp_options: Table is marked as crashed

Hey guys. I was trying to access my website and I had a message “Error establishing a database connection”. Okay, thats not a big problem.

When I tryed to login into the wp-admin, I received a warning message asking me to repair the database and I did. After doing it, the report said that all the tables were fixed but the “wp_options: Table is marked as crashed”.

The website and the wp-admin is now working fine, but I don’t know what caused this problem. Did someone has already received this kind of messages?

Thank you.
