Description:
------------
When using Swagger-PHP to parse API Models with massive docblocks Apache resets the connection. PHP doesn't record any error in the php-error.log. The operating system records the following error in it's log:

Problem signature:

This problem appeared both in PHP 5.4.27 and PHP 5.4.16 both being the 32bit version. I was able to reproduce the issue with both: 
   WAMPSERVER (32 bits & PHP 5.4) 2.4
   XAMPP (1.8.2 / PHP 5.4.27) 32bits

Test script:
---------------
<?php

namespace Controllers\API\Company\RequestModels;

/**
 * @SWG\Model()
 */
class Search {

    /**
     * @SWG\Property(required=true, type="SearchFilter")
     */
    public $filter;

    /**
     * @SWG\Property(required=true, type="string", enum="['active_member.asc','active_member.desc','name.asc','name.desc','jobs_count.asc','jobs_count.desc','cv_download_limit.asc','cv_download_limit.desc','references_count.asc','references_count.desc','last_login.asc','last_login.desc','register_date.asc','register_date.desc','last_comment_date_created.asc','last_comment_date_created.desc']")
     */
    public $sort;

    /**
     * @SWG\Property(required=true, type="integer")
     */
    public $pageNr;

    /**
     * @SWG\Property(required=true, type="integer")
     */
    public $pageSize;

}

Expected result:
----------------
When parsing with Swagger PHP a JSON should be produced.

Actual result:
--------------
Apache resets the connection.
The Operating System logs the following error:
