Redis cleanup doesn't work with Redis 7.4, but it works with Redis 5.0.8.

Well, looks like it actually cleaned up Redis successfully. See the message Finished deleting keys with external storage namespace.

The last malloc(): mismatching next->prev_size seems to be another bug in Ray.

Hi @kevin85421, the e2e helper for checking Redis cleanup has been added in #2773, and all tests pass. However, I didn’t see the malloc message on my side:

I wonder if it is related to the underlying operator system.

Reopening the issue because Ray still requires some fixes.
