Description:
Hello

We are running purge script on old data but yesterday we saw crashes on some of the resources.

Here is some informations attached

We looked at `8.0.37`, 38, 39 changelog but didn't find something that could help us. 

How to repeat:
Because it's a disk corruption we do not know how to reproduce this issue.

It seems it's related to index, when I see in stacktrace `btr_cur_search_to_nth_level` https://github.com/mysql/mysql-server/blob/19feac3674e2ae254b3e7fa7e116fc64ac284d8d/storag...

Can't repeat.

It was not related to the index but to specific row. We ran big count(*) on small range to identify those raws and see how much we were impacted.

RDS can change your innodb recovery if you ask them. If you want to perform a mysqldump after.
