TYPO3 Core

TYPO3 v10 has the feature to change the slug of its subpages when you change the slug of a page. That's exactly what I want TYPO3 to do, however this recursive update is not working when editing a page which has many subpages. In my case, when I edit one of the higher level pages (which has 500+ subpages) TYPO3 runs out of memory and the update is aborted. The slug cannot be changed it seems.

A side effect of this issue is that redirects are being generated because the data handler isn't used to generate them (see #91792). What happens is that pages which have been processed by TYPO3 for the slug update do have a redirect, however because the slug for that page hasn't changed yet in the database (and other places) the page is unresolvable and leads to the 404 error page. To resolve the non-working redirects, I go to the root in the list module and search for the new slug and remove all of the redirects that have been created. This resolves the issue of the non-working redirects, however the problem still exists for changing the slug.
