Chris Herron commented on CASSANDRA-4417: ----------------------------------------- We are seeing large volumes of this error on all nodes when running a load test while also running upgradesstables on multiple CF's on each node. After reading Sylvain's comments above, tried running the same test with commitlog_sync: batch - we get a similar volume of the same errors.
