PHP dies unexpectedly without error

Could someone point me to a list of all the different memory/time/[whatever] limits that can be imposed by PHP? In short, Apache gives me a -103 (ERR_CONNECTION_ABORTED) error when merely instantiating an object with certain parameters. I experienced this first on Rackspace's Cloud Sites platform, and then on my local Windows box. I've yet to see the problem show up on one of Rackspace's CentOS cloud servers.

Other details:

  • The request goes on for about 4 seconds before it dies.
  • The memory usage for the httpd process jumps from ~15M to ~30M during the request.
  • ini_get('memory_limit') returns 264M.
  • ini_get('max_execution_time') return 60.
  • PHP version is 5.4.7.
  • Apache version is 2.4.3.
  • Underlying PHP application is Lemonstand.

Basically, I'm creating a new instance of the Shop_CustomerGroup class which inherits from Db_ActiveRecord. The code dies when the constructor of Db_ActiveRecord tries to create a new instance of Phpr_Validation.

<?php

    class Db_ActiveRecord extends Db_SqlBase implements IteratorAggregate
    {
        // More code...

        public function __construct($values = null, $options = array())
        {
            $this->modelState = self::stateCreating;
            $this->model_options = $options;

            $this->implement = Phpr_Util::splat($this->implement, true);
            array_unshift($this->implement, 'Phpr_Events');
            parent::__construct();

            $this->initialize();
            self::$object_counter++;
            $this->objectId = 'ac_obj_'.self::$object_counter;

            if (!$this->get_model_option('no_validation'))
            {
                if (!empty($options['test'])) {
                    // If I pass in `null`, 'foo' gets thrown. But if I pass in `$this`, the script appears to die.
                    $this->validation = new Phpr_Validation($this, 'test');
                } else {
                    $this->validation = new Phpr_Validation($this); 
                }
                $this->validation->focusPrefix = get_class($this)."_";
            }

            // Fill with data
            if ($values !== null) 
            {
                $this->fill($values);
                $this->fill_relations($values);
            }

            $this->modelState = self::stateCreated;
        }

        // More code...
    }


    class Phpr_Validation
    {

        // More code...

        public function __construct( $Owner = null, $FormId = 'FormElement' )
        {
            if ($FormId == 'test')
                throw new Phpr_ApplicationException('foo');

            $this->_owner = $Owner;
            $this->_formId = $FormId;
            $this->_fields = array();
            $this->errorFields = array();
            $this->valid = false;
            $this->errorMessage = null;
            $this->fieldErrors = array();
            $this->fieldValues = array();
        }

        // More code...
    }

Unless there's something special about passing $this into an object's constructor, I'm convinced I'm running into some kind of limit. I just don't know what that limit might be.

Any help is appreciated! Thanks!

Setting up XDebug and stepping through might give you some useful insights here. - Fabian Tamp
@ItayMoav-Malimovka I'm not seeing any Apache or PHP errors. I updated my original post with the request details and virtual host config entry if that helps at all. - Stephen Bunch
@FabianTamp Thanks, I'll give that a shot tomorrow. - Stephen Bunch
Did you enable the PHP error log? It might be that display_errors doesn't catch the issue in time. - Niels Keurentjes
@Niels Yes, error logging should be enabled. ini_get('error_reporting') returns 32767 (same as E_ALL), ini_get('display_errors') returns 1, and ini_get('log_errors') also returns 1. - Stephen Bunch

You should make sure that your files are UTF-8 without BOM...
