jetpack_sync_cron failed to run
-
Hi
Jetpack reports that the ‘jetpack_sync_cron failed to run’ on my site.
It also takes around two days for subscribers to get alerted after I have published a new post.
I think the two might be related in some way.
Any ideas on what I can do to fix it?
Bruce.

Hi
I have uninstalled Jetpack and reinstalled it again. Same problem.
I also notice the sharing buttons now no longer appear at the bottom of each blog even though they are properly configured.
I forgot to include my site URL :
- http://www.weatherdiary.uk

Hi @xmetman
The issue is likely being caused by how Jetpack uses the WordPress cron system. Can you reach out to your host to have them check to see if cron is enabled and working correctly on your site?
Could you also check your site’s wp-config.php file, and let me know if cron is currently disabled? If it is disabled, you’ll see this bit of code somewhere in that file:
define( 'DISABLE_WP_CRON', true );
Please remove this if it’s present.
Another thing you might try is installing this plugin:
https://wordpress.org/plugins/wp-crontrol/
… which should let you see if there’s anything wrong with your site’s cron system.
Hi
Thanks for your help.
My Host says the CRON is enabled and working.
They also say that the config does not contain the disable command.
I’ve installed wp-control and that’s reporting very long times on some of the cron kobs it runs:-

Hi @xmetman
I’ve just now made a small change and started a full sync of your site again to see if it helps things.
It may take a few hours for the sync to complete.
Hi
Thanks for trying that but I’m afraid it hasn’t fixed the problem!
“One or more (5) cron events missed their schedule”
Bruce.
Hi @xmetman
At this point, I’d like to run some more tests with you on your site to try to figure out what’s happening.
Could you contact us via this contact form and mention this thread?
Seeing this also…something in the 6.x code base isn’t right, because I never saw these errors and warning about caching before. No one wants to see errors on their site health page they can’t resolve or understand. I know cron is working fine on my site (I self-host and many other jobs that use cron work fine). Not sure how wp-cron works or how it interacts with system cron.
Hi Paul
I installed it because the people that host my WP site said that my processes were maxing out. I think their threshold for what I pay is 75%. I contacted a forum and they said it would be a good idea to install wp-cron and then I saw load of amber ! events. My site is slow to save changes that I make to a list in the sidebar, it gets slower the more I add, and get take a couple of minutes to come back and say it’s saved. Changes to my Astra theme in contrast are fine though.
All I can think is that there is a lot of processing being wasted trying to run these cron jobs.
I have had to relent and install Jetpack.
A message to say I’ve posted a new blog to any subscribers still takes days though as it did before.By the way I have only one subscriber – me.
Latest stat show my site is getting a handful of views a day.
My other two sites are fine.
I’ve never had a WP misbehave like this one does.
Bruce.
As I say outwardly to me the site seems fast.
Perhaps it’s the the 75% resource throttling by my host that’s causing cron jobs to fail?
Surely they wouldn’t put that much load on the servers processor if they didn’t run concurrently?My server is very lightly loaded and the wordpress stack (php-fpm, mariadb, nginx) is the main thing it runs. Something happened in this latest release that’s not right and I wonder why it’s taking so long to find it/figure it out. I have been seeing a lot of these errors:
[02-Dec-2022 20:49:28] WARNING: [pool www] child 9811, script '/usr/local/www/wordpress/index.php' (request: "GET /wordpress/index.php") executing too slow (10.738534 sec), logging [02-Dec-2022 23:27:20] WARNING: [pool www] child 10035, script '/usr/local/www/wordpress/index.php' (request: "GET /wordpress/index.php") executing too slow (10.893408 sec), logging
Adding caching seems to have helped but I never needed that before. Not sure why I need to now add a redis process for a low traffic site just to get pages to load.
Howdy @paul,
