Error establishing a database connection

[alpinistory]

Hello. Can You help me? There is a message "Error establishing a database connection" on my mainpage several times a day. I have checked my database - it's ok on the face of it. In what may be the reason?
Thank You.

Please check your site's configuration for a MySQL connection. Make sure that the configuration is correct. Right now, there is nothing wrong with boru MySQL itself.

Thank You! I will try to find a reason myself now. Maybe restoring can help...
