I tried MariaDB 10.5. Both 'consistent increase of the history length'
issue and 'MariaDB stall' issue
happen on MariaDB 10.5.27 like I already tried on 11.4.4 while running
many READ COMMITTED DML and many
REPEATABLE READ DQL queries in parallel.
It is not yet clear which changes between 10.4 and 10.5 cause these
issues.

Are there any parameter to make 10.5 (or later) behave like 10.4 for
these issues ?
Or can they be simply regression bugs ?
