I just tried READ COMMITTED everywhere on 11.4 and I had no such consistent increase of the history length (see the attachment). But it is not an acceptable solution and we anyway had no such issue on 10.4 with READ COMMITTED and REPEATABLE READ combination.
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. https://mariadb.com/kb/en/changes-and-improvements-in-mariadb-10-5/ Are there any parameter to make 10.5 (or later) behave like 10.4 for these issues ? Or can they be simply regression bugs ? Best regards, Kazuhiko
