Public bug reported: I've verified that the following MariaDB issue also impacts MySQL: https://mariadb.atlassian.net/browse/MDEV-6615
[Impact] Data corruption on arm64 (and maybe ppc64el?) [Test Case] Reproducibility varies across SoCs but, at least on one SoC, it reliably fails within seconds with these sysbench commands: sysbench --num-threads=128 --max-requests=0 --max-time=1000 --test=oltp prepare sysbench --num-threads=128 --max-requests=0 --max-time=1000 --test=oltp run On failure, mysql will crash and sysbench will report a connection loss to the database. [Regression Risk] The fix touch some low level locking code, so there is always the risk that it introduces a problem on other platforms. However, this fix has been included in MariaDB since the 10.0.13 release in Aug, 2014 so it has had some real world testing. ** Affects: mysql-5.6 (Ubuntu) Importance: Critical Status: Confirmed -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to mysql-5.6 in Ubuntu. https://bugs.launchpad.net/bugs/1427406 Title: data corruption on arm64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.6/+bug/1427406/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
