Hi everyone, we’re trying to troubleshoot the issues our Discourse installation has been having in the last few days.
We’re running a Contabo cloud vps, 8 cores/32gb/nvme, for a userbase of ~150 people; we’ve had few issues in the last 2 and a half years.
Since last weekend, the instance is having moments of almost-unusability, due to a un unusually high CPU usage.
To troubleshoot this situation, we’ve let the forum in Read Only mode yesterday. I have a few Grafana graphs showing what’s our situation - the three markers indicate where we turned on Read Only, when we restarted the container and when we turned off Read Only.
(a couple more graphs here:
Imgur: The magic of the Internet )
As you can see, usage is pretty high. This started a few days ago, therefore there’s some kind of issue we’ve yet to troubleshoot properly.
After asking the AI assistant before opening a new thread, I can add that Sidekiq has some outlier processes:
Jobs::ProcessBadgeBacklog takes about 2-5 seconds
last DestroyOldDeletionStubs took 475 seconds.
last DirectoryRefreshDaily took 580 seconds.
last TopRefreshToday took 18 seconds.
So, the question is - what could be causing this kind of situation, with the userbase and the hardware we’re using?
Thanks!

I think somehow you’re short of RAM. You have 32G. But possibly you have some process or processes using more than expected.
Perhaps capture ps aux in a window about 120 chars wide. Here’s mine:

I don’t believe there’s any sensitive data there. If you see something, edit it out before posting!

I note in the busy times a lot of system kernel time which often means paging. You can always runvmstat 5 5

This is definitely a memory issue: I’m seeing some huge queries here.
The question, now, becomes “what is causing these queries to be so big”, because it happened suddenly and I assume our case (150 users, 1000 posts per day) should not be having issues with this amount of memory.

Have you rebooted recently?
It looks like there are a bunch of idle postgres processes eating a bunch of memory, I think.
How much memory did you give postgres in your app.yml? Did you change the defaults?
Also, Postgres 13 hasn’t been supported for a year. You really need to upgrade. I didn’t think Discourse would work with PG13 – what version of Discourse are you running?

This doesn’t look like a memory problem to me - there’s only around 6GB taken up by applications. There’s a lot of reading happening, which at a guess I’d say (along with sidekiq being busy) maybe postgres is doing a lot of reading of old data from disk, maybe to do some stats jobs. If the database doesn’t fit in RAM, it’s potentially going to do a lot of reading if that older data is being accessed. That’s what this smells like.

I would look at sidekiq first - I bet it’s busy running updates. Check the /sidekiq url while logged in as admin to see what it’s doing. That’s probably going to show you some long-running update tasks.
You can also, on the SQL server:
SELECT pid, application_name, query
FROM pg_stat_activity
WHERE state IS NOT NULL
AND state != 'idle';
to see what queries are running and what’s calling them. That’ll hint towards what’s causing the load.
Do you have performance headers enabled ? You can turn those on and capture them in logs to let you know how much time Discourse is spending on each part.

The kernel swapd has racked up quite a bit of time. It’s quite possible the paging activity wasn’t captured by the short vmstat run.
There seem to me to be a lot of postgres processes using more or less 20% of RAM. Too many processes given the available RAM?? Checking the postgresql config would be wise.
But a reboot would also be wise before proceeding to re-measure.
As the memory percentages add up to much too much, there must be some sharing which isn’t visible. Still, it seems like a lot of large processes.

Discourse forks after initialisation to benefit from sharing as much as it can, yes.

The situation has improved.
We don’t know what exactly fixed the issue but we’re doing fine now.
The situation seems to be stable now.
Thanks for your help so far.
