# Admin area resets APCu cache

 * I have wordpress installed without any caching plugins.
 * On the same server I have some other apps that save some data and session data
   to APCu user cache.
 * I was having a problem where the cache was being flushed at apparently random
   intervals. After some testing I came to the conclusion that it seems to be wordpress
   that’s reseting the cache.
 * Either navigating the admin area or just leaving the admin area open, my cache
   gets emptied everytime wordpress makes a request to the server. Either directly
   or through a wp-admin/admin-ajax.php (heartbeat?) request.
 * I have no idea why this could be happening. I’m not too familiar with wordpress
   but I always assumed that it wouldn’t use any type of cache unless explicitly
   set? Anyway, everytime I load a page, my APCu uptime goes to 0 and I lose all
   cached variables and sessions on my other app.
 * My server details are:
    Wordpress 4.4.1 APCu Version 4.0.7 PHP Version 5.6.17-
   0+deb8u1 Server Software nginx/1.6.2
 * Any advice or insight would be greatly appreciated.
 * Thank you.

 * Replying to my own post.
 * I further traced this issue to the plugin “better-wp-security” (iThemes security).
 * This plugin calls apc_clear_cache() on two different occasions and this was causing
   our issues. On APCu this seems to clear the entire user cache. (which makes sense
   as APCu no longer has opcode cache)
 * I’ve posted this bug on the plugins’ support forum.

 * Thanks.
 * This hint that the problem could be inside WP
    and not in the OS was enough for
   me to solve my problem.
 * In my case, it was some other plugin.
