Error 122 in storage engine show full columns ‘wp_wfBlocks’ table

Replies: 0

Hi Fellows
This morning while checked my error_log file, i could see this message:

WordPress database error Got error 122 from storage engine for query SHOW FULL COLUMNS FROM wp_wfBlocks made by require(‘wp-blog-header.php’), require_once(‘wp-load.php’), require_once(‘wp-config.php’), require_once(‘wp-settings.php’), do_action(‘plugins_loaded’), WP_Hook->do_action, WP_Hook->apply_filters, wordfence::veryFirstAction, wfLog->firewallBadIPs, wfDB->querySingleRec

Later looked for my wp_wfBlocks table to see how many rows was in it, but it was completely empty.

I’m concern because my error_log file is growing fast and the current size is: 5GB, most of the problem is due to this message.

Some ideas about this error log message and how to fix it?

Thanks
