Moodle version 3.8+ (Build: 20200103) and MySQL version 5.7.32 and using BigBlueButton.
We have logins per day about 2000 and at the same time about 200.
Moodle is hanging every day and display this message "Error: Database connection failed" after restart linux this error disappears and work normally, about a day later this error occurs. What can cause this error? Too many logins at once?
How to solve this trouble? Or resources to increase?
