Thanks to your report, Daniel Black (the author of a contribution that excludes large InnoDB buffers from core dumps) found out that it is a bug in the Linux kernel. His fix will be in the 4.19 kernel, and it was also included in a backport queue for the maintenance updates of older kernels: https://lwn.net/Articles/767784/ https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/commit/?id=c386d043e8e7718b218731b2868453335245ceeb For future reference, I have updated https://jira.mariadb.org/browse/MDEV-10814 with this information. -- Marko Mäkelä, Lead Developer InnoDB MariaDB Corporation _______________________________________________ Mailing list: https://launchpad.net/~maria-discuss Post to : [email protected] Unsubscribe : https://launchpad.net/~maria-discuss More help : https://help.launchpad.net/ListHelp
