Hi everyone,
I am experiencing a critical performance issue where administrative actions in the backend are causing active respondents to be disconnected or receive error pages on a high-traffic survey .

The Problem:
Whenever I refresh the following admin pages:
/index.php?r=dashboard/view (Admin Dashboard)
/index.php?r=surveyAdministration/listsurveys/active/Y (Active Survey List)
Respondents currently filling out the survey immediately encounter errors.

In config.php, I have debug => 2, but the error page only shows a generic "Error" message without a stack trace when this specific crash occurs. How can I force a full debug output for this scenario?
Any help or optimization tips would be greatly appreciated!
