Julien Anguenot commented on CASSANDRA-7612: -------------------------------------------- I actually just found what is causing this reading your comment about the network issue: when a DataStax cluster session at the app level is killed ungracefully it is indeed throwing this error Cassandra side and it makes total sense. I should have thought about that earlier. We just migrated our application from Astyanax to the DataStax CQL Java driver (at the same time as upgrading to 2.0.9) and we did not use to have this stack trace showing up in our monitoring logs when our CI builders were kicking in throughout the day re-deploying our application nodes. Sorry about the noise and thank you very much for your answer.
