*Env: * apache cassandra 2.1.8, 6-nodes
*Problem: *one node had kernel panic and crashed twice this morning. seems
gossip generation was messed up. all nodes are flooded with "received an
invalid gossip generation for peer" warning messages. multiple rolling
restarts only fixed "nodetool status". the warning messages are still
happening. and gossipinfo is showing "shutdown" for some nodes.
*Question: *Does anyone know how to get rid of this warning messages?
take the whole cluster down is not desired as this is production.
