Perform lots of concurrent innodb operations on Power hardware. A per upstream bug https://bugs.mysql.com/bug.php?id=80436 MySQL-5.7 can assert on ppc64/ppc64le (and probably ARM64) because load order between "recursive" and "writer_thread" wasn't properly enforced. Upstream bug report has a patch (originally from MariaDB) that corrects the problem. ** Affects: dbf2mysql (Ubuntu) Importance: Undecided Assignee: Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) Status: New ** Tags: architecture-ppc64le bugnameltc-156946 severity-high targetmilestone-inin--- ** Tags added: architecture-ppc64le bugnameltc-156946 severity-high targetmilestone-inin--- ** Changed in: ubuntu Assignee: (unassigned) => Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) ** Package changed: ubuntu => dbf2mysql (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1706281 Title: MySQL-5.6/5.7 innodb assertion !lock->recursive assert in sync0rw.cc during high load on PPC64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dbf2mysql/+bug/1706281/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
