commit 67984850228f6f26a72504b9f464a5fbcaac59e6 Author: Carl Baldwin <[email protected]> Date: Fri Jul 29 10:10:48 2016 -0600 Avoid IPAM driver reusing a session that has been rolled back With the in-tree pluggable IPAM driver, IPAM rollback tries to use the DB session after it has been rolled back due to an exception. This driver doesn't need roll back, so fix this by adding a method to the driver signalling that rollback shouldn't be attempted.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1603162 Title: Pluggable IPAM rollback fails with reference driver Status in neutron: Fix Released Bug description: This bug is visible when pluggable IPAM is active. It can be seen with this patch [1]. It does not cause gate failures but it is still something that should be understood. This logstash query [2] seems to find where they occur. It is helpful to look at the DEBUG level logging around the time of the error. For example see this paste [3]. It seems that the session gets broken with an exception that causes a rollback. Then, the IPAM rollback attempts to use the same session for rollback which fails. Should the reference pluggable IPAM driver be using a different session? Or, should it call rollback?
