In both error logs, I see this sequence (with varying timestamps and seq numbers, of course):
2015-03-29 15:03:37 2265 [Note] InnoDB: The log sequence numbers 10740390801 and 10740390801 in ibdata files do not match the log sequence number 11404279789 in the ib_logfiles! 2015-03-29 15:03:37 2265 [Note] InnoDB: Database was not shutdown normally! 2015-03-29 15:03:37 2265 [Note] InnoDB: Starting crash recovery. I think that's the core of the problem. 5.5 was not shut down properly before upgrading, so it's left to 5.6 to try to recover. For some reason it can't, and it crashes. -- 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/1437846 Title: akonadi mysql 5.6 crash with signal 11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.6/+bug/1437846/+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
