php - What is the best way to handle "Warning: mysql_connect(): Too many connections" with Kohana 3? -

i've got web application used company logging employees' work.

a lot of people logged in @ once.

the application runs on shared host.

i receive...

warning: mysql_connect() [function.mysql-connect]: many connections

which lets further errors cascade... errors mysql_select_db(), mysql_error(), mysql_errnon() , uncaught database_eexception.

when run main request, wrap in try , capture exception , display not found page. because controllers throw exceptions if resource not found (though route may valid) e.g. http://example.com/products/30 valid route, product #30 doesn't exist.

what best way handle too many connections? ideally i'd capture exception separately, display nice page informs employee try again in 5 minutes.

the code runs main request in application/bootstrap.php looks this...

$request = request::instance();  try {     $request->execute(); } catch (exception $e) {      if (kohana::$environment === kohana::development) throw $e;      // log error     kohana::$log->add(kohana::error, kohana::exception_text($e));      // create 404 response     $request->status = 404;     $request->response = request::factory(route::get('catch_all')->uri(array('path' => 'errors/404')))->execute(); }  $request->send_headers(); echo $request->response; 

thanks help!

i created such file handle errors:

<?php  class kohana extends kohana_core {   /**    * redirect custom exception_handler    */   public static function exception_handler(exception $e)   {     if (kohana::development === kohana::$environment)     {       // pass kohana if we're in development environment       parent::exception_handler($e);     }     else     {       kohana::$log->add(kohana::error, kohana::exception_text($e));        // default route       $route = route::url('default', array('controller' => 'error', 'action' => '404'));        // error sub-request.       echo request::factory($route)         ->execute()         ->send_headers()         ->response;     }   } } 

for sketch, give ideas.

ps: bootstrap not modified
