 * Hi! I’ve started to use WP-optimize recently, and found that slightly after activating
   the plugin it crashes the whole website by using maximum memory and I/O. We have
   512M of mem. limit and 10 MB/s I/O limit.
 * Preloading was not enabled, and there’s no user load at all on this test site.
 * According to the webserver log, it generates hundreds and thousands of calls 
   to [/wp-content/uploads/wpo/server-signature/on/test.php](http://teszt.rcs.hu/wp-content/uploads/wpo/server-signature/on/test.php)
 * If i delete the plugin folder the site comes back to life normally, but if i 
   reinstall WP-optimize it crashes instantly.
 * We’re running on WordPress 6.1.1 and PHP 7.4

 * Hi,
 * Unfortunately I am not able to view the webserver log, can you copy and paste
   some of the entries using a tools such as pastebin.com?

 * Thank you for your quick reply. This is a sample part of Apache log: [https://pastebin.com/wqdkzmV1](https://pastebin.com/wqdkzmV1)

 * Identical problem happens on our webServer (IIS).
 * We found that if you disable Minify the problem disappears.
   As soon as Minify
   is enabled again, several CGI / FastCGI processes (php-cgi.exe) are launched 
   that exhaust CPU and Memory resources.

 * Hi,
 * Apologies for the inconvenience, it appears that WPO is logging the same error
   over and over again, I will ask our development team to look at this as we are
   likely going to want to release a fix for this.

 * [@glezsak](https://wordpress.org/support/users/glezsak/) Please add `define('
   WPO_USE_WEBP_CONVERSION', false);` to your `wp-config.php` file. That should 
   fix the web server log issue.
   Regarding minify, what do you see as `current cache`
   and `total cache` sizes? Does it grow too frequently? Doe sthe `last minify cache
   update` time changes too often?[https://prnt.sc/xRUnZA2f9Ytx](https://prnt.sc/xRUnZA2f9Ytx)

 * Thanks, using `define('WPO_USE_WEBP_CONVERSION', false);` fixed the problem.
