PHP Fatal error: Allowed memory size of 32MB exhausted, in query_factory.php line 486

[jwaynehinkle]

So I am going through my logs and I have for the most part got them all cleaned up however there are a few that are absolutely blowing my mind and I can not put my finger on

PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 36 bytes) in includes/classes/db/mysql/query_factory.php on line 486
this line contains

while (list($key, $value) = each($zp_result_array)) { 

and then in a different log there is this

PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 20 bytes) in /includes/classes/db/mysql/query_factory.php on line 487

this line contains

if (!preg_match('/^[0-9]/', $key)) { 

The entire section of code reads

  function MoveNext() {
    global $zc_cache;
    $this->cursor++;
    if ($this->is_cached) {
      if ($this->cursor >= sizeof($this->result)) {
        $this->EOF = true;
      } else {
        while(list($key, $value) = each($this->result[$this->cursor])) {
          $this->fields[$key] = $value;
        }
      }
    } else {
      $zp_result_array = @mysql_fetch_array($this->resource);
      if (!$zp_result_array) {
        $this->EOF = true;
      } else {
        while (list($key, $value) = each($zp_result_array)) {
          if (!preg_match('/^[0-9]/', $key)) {
            $this->fields[$key] = $value;
          }
        }
      }
    }
  } 

and then there is this one

PHP Warning: Illegal string offset 'cost' in /includes/classes/order.php on line 384

this line is

'shipping_cost' => $_SESSION['shipping']['cost'], 

the entire section of code is

$this->info = array('order_status' => DEFAULT_ORDERS_STATUS_ID,
                        'currency' => $_SESSION['currency'],
                        'currency_value' => $currencies->currencies[$_SESSION['currency']]['value'],

                        'shipping_method' => (is_array($_SESSION['shipping']) ? $_SESSION['shipping']['title'] : $_SESSION['shipping']),
                        'shipping_module_code' => (isset($_SESSION['shipping']['id']) && strpos($_SESSION['shipping']['id'], '_') > 0 ? $_SESSION['shipping']['id'] : $_SESSION['shipping']),
                        'shipping_cost' => $_SESSION['shipping']['cost'],
                        'subtotal' => 0,
                        'shipping_tax' => 0,
                        'tax' => 0,
                        'total' => 0,
                        'tax_groups' => array(),
                        'comments' => (isset($_SESSION['comments']) ? $_SESSION['comments'] : ''),
                        'ip_address' => $_SESSION['customers_ip_address'] . ' - ' . $_SERVER['REMOTE_ADDR']
                        ); 

Then here is another one

PHP Warning: Creating default object from empty value in /includes/modules/shipping_estimator.php on line 92

this line contains

$order->delivery = array('postcode' => $zip_code, 

then in a different log there is this one

this line contains

$country_info = $_SESSION['country_info']; 

this entire section is

    } else {
      // first timer
      $_SESSION['cart_country_id'] = STORE_COUNTRY;
      $_SESSION['country_info'] = zen_get_countries(STORE_COUNTRY,true);
      $country_info = $_SESSION['country_info'];
      $order->delivery = array(//'postcode' => '',

                               'zone_id' => $state_zone_id,
                               'format_id' => zen_get_address_format_id($_POST['zone_country_id']));
    } 

Any help would be greatly appreciated.

Thanks in advanced fellow Zenners!
