MySQL Error : Connection Error

[Chip D]

I don't seem to be having a great deal of luck with a particular site that I'm working on. The latest problem is that the Guest Book (Advanced Guestbook 1.0) has suddenly decided to die! I was alerted to the problem by an automated email generated by the script. The error that it is saying is MySQL Error : Connection Error. When I actually visit the page the error that is produced is as follows,

Warning: Too many connections in /export/home/atlantic/www/guestbook/include/mysql.inc.php on line 8
Connection Error

The offending code in the file mysql.inc.php is shown below.

<?php

class db_sql {

  var $conn_id, $result, $record;

  function connect ($host,$user,$pwd,$dbname) {
    $this->conn_id = mysql_pconnect($host,$user,$pwd);
    if ($this->conn_id == 0) {
      $this->sql_error("Connection Error");
    }
    if (!mysql_select_db($dbname, $this->conn_id)) {
      $this->sql_error("Select DB Error");
    }
    return $this->conn_id;
  }

  function query($query_string) {
    $this->result = mysql_query($query_string,$this->conn_id);  
    if (!$this->result) {
      $this->sql_error("Query Error");
    } 
    return $this->result;
  }

  function fetch_array($query_id) {
    $this->record = mysql_fetch_array($query_id,MYSQL_ASSOC);
    return $this->record;
  }

  function free_result($query_id) {
    return mysql_free_result($query_id);
  }
  
  function sql_error($message) {
    global $admin_mail,$sql_hostname;
    $description = mysql_error();
    $number = mysql_errno();
    $error ="MySQL Error : $message\n";
    $error.="Error Number: $number $description\n"; 
    $error.="Date        : ".date("D, F j, Y H:i:s")."\n";
    $error.="IP          : ".getenv("REMOTE_ADDR")."\n";

    $error.="Referer     : ".getenv("HTTP_REFERER")."\n";
    echo "<b><font size=4 face=Arial>$message</font></b><hr>";
    echo "<pre>$error</pre>";
    @mail("$admin_mail","Guestbook - Error","$error","From: guestbook@$sql_hostname\nX-Mailer: Advanced Guestbook");
    exit();
  }

}

?>

PHP version installed on the server is 4.0b4pl1 and MySQL Version is 3.22.32. Persistent connections are allowed and are unlimited as well. I do have access to PHP Vers 4.0.5-dev and MySQL vers 3.23.36, but that does involve a bit of code hacking, which I can do, but don't want to have to if possible.

At the moment due to time constraints, my knowledge of PHP/MySQL is very much on a need to know basis.

If anyone could elaborated on the above then I would be very grateful.

Many Thanks,

UPDATE: D'oh! Just noticed that it's not just the guestbook script thats suffering. ALL of the scripts that I use, that access MySQL are suffering from the same errors. Time to contact support me thinks.
