failed to open dir: Too many open files

Hi,

I just installed cwp and orocommerce. Then I tried to run a command line php app/console cache:clear --env=prod. It is giving me failed to open dir: Too many open files error. I modified the php conf max_input_nesting_level = 1500. It didn't help.

  [UnexpectedValueException]                                                                                                 
                                                                                                                             
    RecursiveDirectoryIterator::__construct(/home/realized/public_html/oro/vendor/oro/commerce/src/Oro/Bundle/PaymentBundle/ 
  Resources/translations): failed to open dir: Too many open files

Thanks
