Agent creates a 502 on cache clear within WordPress Admin #988

Closed 6fears7 closed 1 year ago

6fears7 commented 1 year ago

Describe the bug When clearing cache using the popular W3 Total Cache plugin while APM agent is active (latest version, but older versions too), the page will react in one of three ways. One, by throwing a large number of APM errors within the plugin page. Two, by displaying a critical error on the page (along with the DB login info). Three, a generic Nginx 502.

  3. image

All of these will resolve after page refresh.

When the APM agent is disabled, cache clear behaves normally.

Notable logs during that time:

myContainer | 2023/06/08 20:23:46 [error] 27#27: *101 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 172.22.0.1, server: , request: "GET /wp-admin/admin.php?page=w3tc_dashboard&w3tc_note=flush_all HTTP/1.1", upstream: "fastcgi://unix:/tmp/.php-fpm.sock:", host: "localhost:8080", referrer: "http://localhost:8080/wp-admin/admin.php?page=w3tc_dashboard&w3tc_note=flush_all"

Notable errors on page during that time:

Warning: Invalid callback \Elastic\Apm\Impl\AutoInstrument\PhpPartFacade::interceptedCallPreHook, class "\Elastic\Apm\Impl\AutoInstrument\PhpPartFacade" not found in /var/www/html/wp-includes/class-wpdb.php on line 2431

Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/wp-includes/class-wpdb.php:942) in /var/www/html/wp-admin/includes/misc.php on line 1431

Really nothing weird being output by the Agent logs, even in Debug mode.

To Reproduce Steps to reproduce the behavior:

  1. Running two containers: WordpressDB:mysql:8, and Wordpress:latest.
  2. Set up the APM agent via your preferred method to run in the Wordpress container (I used APK, but it occurs via other methods too)
  3. Login to your local wordpress env and install the W3 Total Cache plugin, activate it.
  4. Run "clear all cache" or "clear op cache"
  5. Errors should throw.

Expected behavior Cache clearing handled gracefully

This has been ongoing for at least 6 months since we adopted the PHP APM agent, took a look at the repo but I'm not a PHP guru so my own solutions were lost. I've tried altering timeouts on all systems, increasing / decreasing workers, other system management techinques, etc.. but I can't escape the error.
