We have an issue where posting a featured image to a blog post takes the WordPress site down (giving the 'Error establishing a database connection' message) and makes the server unresponsive for between 20-40 mins! The site comes back and the featured image is in place.
We have disabled all plugins and the theme, but can not identify a specific plugin that is causing the issue as it may or may not occur with plugins disabled/enabled (and the theme disabled), there seems to be no obvious patten or relationship with the plugins.
We are running two completely separate installs (one for development) and have now managed to be successful in taking down both, much to the ire of our managers!
Our IT team tells me that the system becomes completely unresponsive and inaccessible, and multiple 'processes' are being created, causing the system to grind to a halt.
This appears to have originated after the update to 3.8, and has persisted since. We seem to have been misguided thinking that this was caused by either the theme or plugins, which have been updated/disabled since. It’s quite staggering that we manage to take down the entire system.
We have noted one other anomaly that can occur, we do not know if this is related. Occasionally the featured image is missing, scrutinising the code shows the following.
The code for the correctly displaying featured image (on our homepage) is:
[ Moderator note: Code fixed, please wrap code in backticks or use the code button. ]
<img src="https://[website]/wp-content/uploads/2014/04/image-100x75.jpg" data-rel="https://[website]/wp-content/uploads/2014/04/image-200x150.jpg" width="100" height="75" alt="Alt text" class="wp-post-image" pagespeed_url_hash="1398416865">
And the broken code is:
