    Description

      Hello, we've made a report on https://jira.mariadb.org/browse/MDEV-33208 in a comment on the latest available build, but it suddenly got closed, so I'm remaking it on a separate Jira.

      Hello, we recently experienced a similar issue on one of our servers running 10.11.7, which had an entire instance remade with logical dumps yesterday. MariaDB Server starts with innodb_force_recovery=2, but innodb_adaptive_flushing=OFF doesn't help to start without it in our case.

      Check table returns `OK`.
      I've uploaded core dump and related data to FTP server, I hope it helps.
