Mcrypt_create_iv () Call not successful, timed out?

Download website source code always error:
Fatal error: Maximum execution time of 30 seconds exceeded in
Finally, locate the call to this sentence:

$iv = mcrypt_create_iv($this->getIvSize(), $this->getRandomizer());

Test file
test.php:

  
   ";$r = MCRYPT_DEV_RANDOM;echo $r;mcrypt_create_iv(1,$r);echo "---------end";?>

Run results

hello-----0Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/test.php on line 5

Tears eyes for guidance!!!

Note:
1. I run on my own Win7 is OK, error is the Ubuntu server, Environment: Ubuntu 12.04 apache2.4 php5.5.28
2. The attached phpinfo,mcrypt should be installed properly. , huh?
