The last time I suffered a huge memory leak in PHP was with HTML Purifier on PHP 5.2. It was impossible to process more than a few documents at a time, even from the CLI, because HTML Purifier seemed to leak every byte of memory it used. Lots of circular references. With PHP 5.3 with the new GC and the latest version of HTML Purifier, there is no memory leak anymore. PHP has come a long way since the days when you had to respawn Apache processes every 500 requests.
