Hello, this is my first post here.
I have this page error every a few days (approximately every 3 days, but not that constant):
Currently, I'm on
- Moodle 3.10+ (Build: 20201224) // but the problem has been persisting since 3.9+
- PHP 7.4.6
- MariaDB 10.4.11
I found this topic problem very similar to mine:
Unfortunately, after following through with all the steps and FAQs, including the solution in that post, I can't find the culprit. I think the uniqueness of the problem is the periodic occurrence of the problem. Restarting the server completely bring back moodle up and running normally.
Looking at the server dashboard, the failure might be the result of high CPU usage which peaks in a very short time before the error. Strangely, both the Apache log and SQL error log were left blank a few hours before the CPU peak.
Any idea of where should I look for the cause?
Thank you in advance for all your suggestions,
/* for longer history: our institute has been using Moodle 2+ for many years, and is still running fine on another server. We start testing out Moodle 3.9 around 6 months ago. We faced many errors which had been fixed throughout these months. Honestly, I can't remember what I have done! (what a bad admin). After all the mess and hair pulling, this error keeps occur. */
