First, I found this article.

I set the site Debugging mode and downloaded the csv file.
In a downloaded file, I could read something like this.

I set the site Debugging mode and downloaded the csv file.
In a downloaded file, I could read something like this.
Allowed memory size of 536870912 bytes exhausted (tried to allocate 112385280 bytes) in xxxxxxx/lib/dml/mysqli_native_moodle_database.php
Mine was gradebook result anyway, and I see the course size is above 1.2G or some.
My memory_limit of php.ini was just 128M, so I set it to 2048M.
I reloaded httpd and php-fpm.
Now I could download the whole grades as a csv file.
Great!
