PHP DNS caching

[hobbes]

Does the PHP engine at FQ cache ip resolution requests (standard behavior (http://us2.php.net/manual/en/function.gethostbyname.php#64070)), or does the cache get cleared out more frequently than when the Apache engines are restarted (rarely)?

The Apache/PHP engines are reset every night at 1:50am ET to prepare for the STATS run...

Also, consider that the Apache children die off and respawn after a certain number of requests... Therefore there is a certain amount of randomness when PHP's DNS caching is flushed...
