 * Hello,
 * first, thank you for taking the time to read me.
 * I wrote a plugin, doing in average one thousand requests each 5 minutes, using
   cron. It’s a lot I know but it’s not to brute force a form, DOS a server or spam.
   It’s only to crawl the Apple App Store to detect prices drops, updates and new
   releases using their API.
 * I disabled cron to execute it server side to be sure to not impact visitors. 
   Using `define('DISABLE_WP_CRON', true);`
 * Everything works perfectly BUT sometimes my cron script return an error, hopefully
   cron notified me by email :
 *     ```
       PHP Warning:  require_once(/home/www/wp-includes/Requests/Response.php): failed to open stream: Too many open files in /home/www/wp-includes/class-requests.php on line 146
       PHP Fatal error:  require_once(): Failed opening required '/home/www/wp-includes/Requests/Response.php' (include_path='.:/usr/user/php/7.2.9/lib/php') in /home/www/wp-includes/class-requests.php on line 146
   
       Warning: require_once(/home/www/wp-includes/Requests/Response.php): failed to open stream: Too many open files in /home/www/wp-includes/class-requests.php on line 146
   
       Fatal error: require_once(): Failed opening required '/home/www/wp-includes/Requests/Response.php' (include_path='.:/usr/user/php/7.2.9/lib/php') in /home/www/wp-includes/class-requests.php on line 146
       ```
   
 * This error does not occurs every time my cron script is executed, but only some
   times (~1 time each 2 hours). If someone can help me to debbug this problem, 
   that would be awesome.
    FYI, I already read some things about `ulimit`, but I
   don’t want to change it.
 * Thanks for your time, sorry for my english I’m french.

 * There are a number of possible open file limits besides the per user limit (ulimit).
   Any one of them could be the cause. Assuming they all are set to reasonable levels,
   the file limit issue is often due to poor coding practice where opened files 
   are not promptly closed when the file is done with. This issue can be less than
   obvious when looping and recursive code is involved. Be sure none of your code
   is abusing the file system in this way. If that checks out, verify the file system
   limits are reasonable. ulimit is only one aspect of this.

 * Hello,
 * thanks for your reply but I never open/write any file in my script/loop, I only
   use `Requests::request_multiple` to fetch JSON data and compare it to my database
   using `wpdb->query`.
    I suspect `Requests::request_multiple` or Curl to put the
   header or the body into a file in `/tmp` folder.
 * FYI, this error does not occurs if I use php function `file_get_contents`, but
   by using this function my script is no longer async and much slower to be executed(
   10 secondes VS 4 minutes).
 * Regards

 * Hmmm. I don’t think `Requests` normally writes to files unless it is explicitly
   told to do so in the options passed. Maybe if PHP is running short of memory,
   some of it is paged out to the file system? Could you perhaps reduce the number
   of requests made through `request_multiple()`?
 * It seems server resources are being maxed out for whatever reason. Your only 
   options are either to reduce the load or increase resources. Of course how that
   is done covers a broad range from a mere setting to better hardware. Without 
   knowing any specifics, it appears to me like reducing requests is what you have
   the most control over.
