I am a Linux beginner, and I have been running PLESK Lightsail instance for 2 years for my organisation's website running WordPress. Yesterday The CPU utilisation suddenly constantly exceeded the Sustainable zone. When looking at the TOP command processes, I saw that the PHP & php-fpm are taking almost 100% CPU. They are not reduced even when I closed ports 80 and 443. I have tried to stop apache and nginx too, but the PHP and php-fpm were still running.
Curiously, the website is still running and accessible.
I also can't login to PLESK, receiving this message after I click submit button:
Server Error
500
Error
Class 'PleskExt\Monitoring\Helper\CloudMonitoring' not found
Type Error
Message Class 'PleskExt\Monitoring\Helper\CloudMonitoring' not found
File CustomButtons.php
Line 49
I tried to use PLESK repair utility but it doesn't seem helping much, after I enter command "plesk repair all -y" the screen just freeze and I can't do anything with the terminal.
Have any of you experienced this?
Thanks!
Hi Dave, After some investigation, I found a list of possible disk space problems. However, the main storage seems okay since it still has plenty of space: /dev/xvda1 on / 574.49 GB of 620.35 GB total
Maybe the one I listed below was the cause? Btw I'm running Ubuntu 18.04 with Plesk 18.0.20. Any idea how to increase the storage below? /dev/loop0 on /snap/amazon-ssm-agent/5656 0.00 B of 25.13 MB total /dev/loop1 on /snap/core/13886 0.00 B of 115.00 MB total /dev/loop2 on /snap/core/13741 0.00 B of 115.00 MB total /dev/loop4 on /snap/amazon-ssm-agent/6312 0.00 B of 24.50 MB total /dev/loop3 on /snap/core18/2560 0.00 B of 55.63 MB total /dev/loop5 on /snap/core18/2566 0.00 B of 55.63 MB total
