This a hanging MySQL bug reported against 5.0.70, 5.1.30 and 5.5.0 that I just ran into with MariaDB 5.1.39. A long running DDL plus a kill plus making heavy use of insert delayed for ad serving resulted in a hang and a processlist just like the one shown in the MySQL bug report: http://bugs.mysql.com/bug.php?id=41114 I'm not sure if it is still present in the current MariaDB but there is a test case attached to the bug: |

According to comments in the upstream bug, the problem was reproducible on 5.5.0, but not on 5.5.10 (most likely got fixed along with MDL changes which were pushed around 5.5.3). |
