Issue "Memory usage is critical" – No matter what I do...

Hi everyone!

I keep getting warnings that my RAM is “critically low.” I know this, and I’m totally fine with it. I have 8 GB of RAM and don’t need notifications telling me there’s “only” 1.85 GB free.

I’d like to change these warnings so they only trigger when it drops below 1 GB.

So I go to Monitoring > Threshold settings and lower the values — but no matter what I set, I still get the warnings. It’s getting pretty annoying…

See the attached screenshot for my current settings.





I’m guessing the changes aren’t saving, because after I click Apply, I get an unreadable error message that looks like this.




What should I do?

5% seems a bit low, maybe try something like 30% or more? Else the warning will be triggered if a service like Apache uses more than 5% of your RAM, and at 8 GB that is very likely to happen.

I have now turned off all settings, I'm still getting warnings. 50 to 100 emails per day.

Any ideas?

I also had the problem that the monitoring was off, but I still got mails. It seems like the last set value is still used. So you have to set a very high value, which is never reached, save this setting and then disable the specific monitoring. I can't guarantee that this works, but it's worth a try.
