Error message with phpbb3 board

[rareyush]

General Error
SQL ERROR [ mysql4 ]

Too many connections [1040]

An sql error occurred while fetching this page. Please contact an administrator if this problem persists.

I have no idea how to put a stop to this, my forums locked up and would not load properly. When something finally did happen it was a blank white screen with no error message.

Any suggestions as to how fix it?

tell me the site name mate
