Created attachment 559018 [details] Proposed patch from flatiron git branch Description of problem: Accordig the totem protocal, nodes should enter GATHER state when it receive JoinMSG in OPERATIONAL state. If we discard it in OPERATIONAL state, the nodes sending this JoinMSG could not receive the response untill other nodes reach token lost timeout. This bug will cause nodes having entered GATHER state spend more time to rejoin the ring, and then it will make nodes reach token expired timeout more easily. Version-Release number of selected component (if applicable): flatiron How reproducible: In description, very ard Steps to Reproduce: 1. In description Additional info: Very hard (almost impossible) to objectively reproduce. Recomended sanity only testing.
