Created attachment 520977 [details] Backported patch from corosync a memb_join operation that occurs during flushing can result in an entry into the GATHER state from the RECOVERY state. This results in the regular sort queue being used instead of the recovery sort queue, resulting in segfault.
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Under certain circumstances, the previous version of OpenAIS sometimes used an incorrect sort message queue when the "memb_join" message was sent during recovery. With this update, this error has been fixed, and OpenAIS now uses a correct sort message queue in this scenario.
