Hi there!
Since I upgraded to nextcloud 11,
I 'm having some considerations about the nextcloud’s background cron job eating my server ressources.
Heres the facts
I’m running nextcloud in a OVH VPS with 1 vcpu and 4GB of ram.
here’s what I see in supervision:
> CPU consumption

Blue : dec 1rst,I switched the cron from ajax to crontab
Red: Dec 15th, Upgraded to nextcloud 11.

> What’s happening on the server:

I have killed the process manually some times (as you can see on the previous graph)
but as this is recurrent, it need further analysis.
I’m not saying this is a bug, it could be a lot of things…
I need some advises for debugging, as I have no skill in PHP (yet).

Regards, Aal.

Can you share with us more about your configuration, what apps are you using? External storage? Can you post the content of the nc_jobs-table? Any errors in your logfile?

Hi @tflidd,
An hour after posting, I’ve read that Nextant has an issue about php cron job in version 1.0.0.
As I use it, I disabled the app for now and I’ll see If the problem persist.
I suppose that nextant register it self (in the oc_jobs table probably) to the nextcloud cron job to be run once a day.
that would explain why the cron job uses 100% CPU only once a day in v10 while it is launched every 15 minutes by the crontab.
Otherwise, I haven’t seen any errors in the nextcloud’s logs that would refer to the cron job.

here’s the content of the table :

That sounds like the problem. Just wait another day and mark your last answer as solution.

Hi,

I had this problem too. You can update to Nextant 1.0.1
No more hanging cron jobs :slight_smile:

Hi, @guddl, thank you for your answer,
I keep the apps up to date and, in fact, nextant was already in 1.0.1 when a created this topic.
On the last few days, I have probed my server while nextant was deactivated and had no performance “issues”.
since yesterday, I have reactivated Nextant and observed the same performance issue today.
my conclusion is that the issue is not with nextcloud but with nextant, but, as I upgraded nextcloud & nextant the same day and didn’t kwown how the cron.php worked, i could figure it out.

So i’ll try to edit the topic for support with Nextant, or close it if I can’t.

Thank you for your support all! :slight_smile: :+1:

Edit : in fact I’m using nextant 1.0.3 now and the problem is still here
