Mysql (can't Connect, Too Many Connections)

[The_Boss]

So that's the error log :

Can't connect to database! Too many connections Line 114 : mysql.class.php

Normally, in morning to evening, my database works fine, and i can access to my website, but, in the night, i can't access to it (the page loads eternally) and 1 or 2 hours after, i got the error.

Yesterday, it works fine at 07:50:06 (France time), so the error continued from the night, to 7h.
Please help me, i have some visitors in the night !

Thank you. (ans sorry for my bad english)

Hi .

112 : if($errors_management)
113 : {
114 : $this->_error('','Can\'t connect to database!',__LINE__,__FILE__);
115 : }
116 : else
117 : {
118 : return CONNECTION_FAILED;
119 : }

I think it's because simultaneous connections, but how i fix it ?

Thank you ssfdre38 !
