I mechanically created a large quiz (using a program to migrate question content from another system). The resulting quiz with all of the automatically generated variants of questions and answers has ~513 questions in it. I can export it (as a QTI.zip file) and load it into the production, test, and beta environments. However, all of these environments generate a page timeout when loading the page when I attempt to edit the quiz. The error message will be of the form:
The xxxx.beta.instructure.com page isn’t working
xxxx.beta.instructure.com took too long to respond.
