WordPress database error Duplicate entry

Hi @rfischmann

Thanks for that, feedback is very important. I will write here as soon as I find the solution.

Just pasting new logs from today that might maybe help identify the issue:

Hi @rfischmann

Thanks, Rafael, I will take this into an account!

I hope that’s helpful.

Here’s another one I just caught in another debug file:

[05-Oct-2024 12:13:47 UTC] PHP Deprecated:  uksort(): Returning bool from comparison function is deprecated, return an integer less than, equal to, or greater than zero in /home/macmagazine/public_html/wp-content/plugins/fulltext-search/includes/wpfts_tokencollector.php on line 173

Hi @rfischmann

Thank you, it’s also very useful observation. Although “deprecated errors” are not dangerous for work, they need to be identified and fixed in a timely manner. Will be fixed in the next release.

Thank you!

@epsiloncool You’re welcome! Thanks.

Just a new heads-up, @epsiloncool, these errors are still all over the place in our logs. Just a few examples:

Hi @epsiloncool,

So for a few months, every now and then, we observe quick database connection errors to WordPress which usually last just a few seconds — no more than 1-3 minutes. We see an error very similar to this one: https://www.hostpapa.com/knowledgebase/app/uploads/2017/09/1-6.png

While that happens, I don’t see anything weird on my server’s monitoring tools. MySQL stays up, CPU and memory don’t spike… so, up until today, I haven’t looked deeply into it.

Today, I’ve decided to carefully search through my logs after it happened again and found the culprit:

[14-Feb-2025 18:57:42 UTC] WordPress database error Lock wait timeout exceeded; try restarting transaction for query UPDATE wp_options SET option_value = '2025-02-15 15:56:52', autoload = 'off' WHERE option_name = 'wpfts_detector2_message_expdt' made by require('wp-blog-header.php'), require_once('wp-load.php'), require_once('wp-config.php'), require_once('wp-settings.php'), include_once('/plugins/fulltext-search/fulltext-search.php'), WPFTS_Core->Init, WPFTS_Core->FeatureDetector, WPFTS_Core->set_option, update_option

Any idea why is that and how to fix it?

Thank you!

Hi @rfischmann

Thank you for this report again!

Please could you try to execute this MYSQL query on your website and tell me what does it show?

SHOW VARIABLES LIKE 'lock_wait_timeout';

Also, since your DB regularly fails to connect clients, I would check the number of allowed simultaneous connections in the my.ini settings. It seems that the DB is working at the limit of its capabilities and therefore periodically “freezes”.

It would be good to look at all the DB settings. They can be obtained by the query

show variables like '%';

Although there is a large list.

It is interesting that this error occurs on your site and no one else’s. Other clients complain about slowdowns with a large number of administrators. We are fixing this.

Thanks!

Sorry for the delay, @epsiloncool.

As for the first query, it just showed one result: https://d.pr/i/nKcE23

I believe these are our current general configuration: https://d.pr/i/hpGIYU

Thanks!
