We are currently experiencing a timeout issue when attempting to use the "Regrade all" function in our LMS.

Details:

• Total quizzes in LMS: Approximately 89,000

• Specific course: Contains 40 quizzes

• Enrolled users in the course: 19

• Problematic quiz:

• • Number of questions: 9

• • Number of attempts: 16

When we click "Regrade all" for this quiz, the system returns a 504 Gateway Time-out error. Given the relatively small number of questions and attempts, this result is unexpected. This issue is in Moodle 4.1.1

Request:

Could you please investigate and suggest a solution or workaround for this issue? If performance optimization or background processing is possible for the regrading task, we would appreciate guidance on implementing that.

Thank you for your assistance.
