Jobs::PeriodicalUpdates is the cause of high CPU (over 100%) When we check: sidekiq/scheduler/history I see, Jobs::PeriodicalUpdates reached 79 secs. Causing the CPU to increase, users accessing the website are out. Does turning off Jobs::PeriodicalUpdates have any effect? How to turn off? And, Jobs::AboutStats ; Jobs::DestroyOldDeletionStubs ; Jobs::DirectoryRefreshDaily ; Jobs::EnsureDbConsistency also causes CPU to go high above 100% How do I resolve these errors?

What is your hardware, ram, SSD? How big is your database? How many posts?

we have about 600k topics. 400GB SSD, 16 core CPU. About Ram, I don’t see full. I get these errors when I rebuild discourse (it was fine before rebuild).

Hope everyone helps. Can anyone tell me: in the Jobs::PeriodicalUpdates . task What do you think this Jobs::PeriodicalUpdates means? Is it possible to disable Jobs::PeriodicalUpdates?

I think this is the list of tasks used by this job: discourse/app/jobs/scheduled/periodical_updates.rb at 1472e47aae5bfdfb6fd9abfe89beb186c751f514 · discourse/discourse · GitHub I’m not an expert to analyse this, I see two settings mentionned automatically download gravatars, I don’t thnink it would explain a high CPU usage rebake_old_posts_count this one is now hidden, but maybe you did set up a lot of old posts to rebake every 15 minutes months ago. It would explain this cpu usage a bit more

I see, after 15 minutes, periodicupdates running. If this is the cause, how can I turn off: rebake_old_posts_count ?

Was the the first upgrade on a long while? I think that you’re likely resizing images due to a change a while back. It’ll work out beeper long.

my last upgrade, was 2.7.x (I don’t remember the exact number of x) hope someone can help me

:slight_smile: I believe there is a way to handle the error, It’s just that my level of technology is limited.

You can’t turn it off. There have been changes that require a rebake. If you have enough resources you might be able to adjust things to improve performance.
