>rpc_address: 0.0.0.0 , broadcast_address: 1.2.3.4 Did you try set rpc_address to node IP and not to 0.0.0.0 ?
Best regards, Vladimir Yudovin, Winguzone - Cloud Cassandra Hosting ---- On Thu, 24 Nov 2016 04:50:08 -0500Jeff Jirsa <jeff.ji...@crowdstrike.com> wrote ---- Did you already try doing what the error message indicates you should try? Is there anything in the logs on the 3 cassandra boxes listed (192.168.198.168, 192.168.198.169, 192.168.198.75) that indicates they had problems at that time, perhaps GCInspector or StatusLogger messages about pauses, or any drops in network utilization to indicate a networking problem?
