We have a site that has 240K posts and regularly DB connections jump from 25 to 250 and 350 until DB server chrashes and we get error 502 “Unable to establish a database connection”.
We resized the DB server which helped just a little but following day crashes started again.
The site has WP Rocket, Sucuri and Redis object & page caching set up, and even on some pages we have block cache enabled. It doesn’t seem like a frontend problem because page speeds are okay but rather a DB problem.
This started happening after theme update to v12.
Any help would be appreciated because site is basically unusable every 2 or 3 days when this happens and manual intervention is needed every time.
Hello,
I apologize for the delay.
Do you have set the block on the page to be sorted by popularity? If yes, then please do a test and don’t use this option and check after.
Thank you!
