Have you ever seen an error log like the one below?
<blockquote>
PHP Fatal error: Allowed memory size of xxxxxx bytes exhausted (tried to allocate xxx bytes) in /var/www/wordpress/wp-includes/wp-db.php on line 2007
</blockquote>
This means that <a href="https://www.php.net/manual/en/ini.core.php#ini.memory-limit" rel="nofollow ugc">PHP memory limit</a> is exhausted while retrieving data from a database. In any case, this happens when your site has big data and makes insane loops inside.
But we want to know that which plugin tried to retrieve data?
Hagakure adds extra information to error.log file when <code>wp-db.php</code> causes memory limit error:
<pre>[08-May-2019 10:28:37 UTC] wpdb Error Backtrace:

This log will always follow the memory limit Fatal Error by <code>wp-db.php</code>. Now you can find <code>#8</code> calls <code>get_posts</code> repeatedly.
We recommend watching logs with notification services like <a href="https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html" rel="nofollow ugc">CloudWatch Logs</a>. 
This error occurs in the productional environment, and you may not have a chance to see it occurs. 
We use Hagakure with our <a href="https://hosting.kunoichiwp.com/" rel="nofollow ugc">hosting service</a>, please look forward to seeing <a href="https://kunoichiwp.com/blog" rel="nofollow ugc">our blog published</a> and describing the integration!
This plugin also adds debug backtrace to error logs. To modify the error level to a detailed backtrace, define the constant in <code>wp-config.php</code> or somewhere else:
<pre>define( 'HAGAKURE_ERROR_LEVEL', E_NOTICE | E_USER_WARNING | E_WARNING | E_USER_ERROR );</pre>
Besides that, if <code>SAVEQUERIES</code> is set <code>true</code>, the slow query log will be logged with PHP debug backtrace. This helps you to debug.
