Re: [support] Druapal server fatal error: "MySQL server has gone away", but DB server is still up & accessible. Help troubleshooting?

unless I'm misinterpreting, it's -- as suspected -- a mariadb issue, independent of drush version, and specific to MariaDB v10.0.11, https://mariadb.atlassian.net/browse/MDEV-6340?focusedCommentId=52062&page=c... working on it there.
