opcache causando erros: Tamanho da memória permitida e malloc: *** erro para o objeto 0x10b4cbaf8: o ponteiro sendo liberado não foi alocado

Question

Desde que instalei o opcache, estou recebendo esses erros:

[Thu Jun 04 17:31:02 2015] [error] [client 127.0.0.1] PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 4485046248 bytes) in Unknown on line 0

Estou usando o Zend Server com o Apache.

Versão do PHP 5.4.21

Aqui estão meus conf:

[opcache]
zend_extension="/usr/local/zend/lib/php_extensions/opcache.so"
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1

Quando tento recarregar minha página phpinfo.php, ela fica em branco.

O que está causando esse problema e o que eu esqueci ou precisei fazer?
