Description of problem: If a commit token is created such sa: node=1 aru=1 ringid=4 node=2 aru=1ef ringid=8 node=3 aru=1fb ringid=8 node=4 aru=1fe ringid=8 What should happen is node 4 should resend all messages from the lowest aru 1ef to the highest aru 1fe. It does this through the setting of a received flag in the commit token. Today this received flag is not always set properly. What happens now is that node2 will not be delivered messages 1fa-1fe, node 2 will not be delivered messages 1fb-1fe. This results in message loss and possible corruption of information multicast when using services like CPG or EVS. Version-Release number of selected component (if applicable): openais-0.80.3-19.el5 How reproducible: more reproducible with a larger cluster, but requires manual inspection of the commit tokens. The keys to reproduction are that every node must be sending traffic and there must be atleast 4 nodes with 1 node being killed/restarted. Could result in a segfault, but I'm not certain about this. Does not fix the checkpoint bug. Definately violates EVS. Steps to Reproduce: 1. 2. 3. Actual results: messages are lost. Expected results: messages should not be lost. Additional info: patch to fix problem in hand and has passed Andrew Beekhof's crm testing suite which verifies messages are correctly sent for 500 iterations including node kills/restarts.
