---------------------------------------

             Summary: AssertionError: null in Slice$Bound.create
                 Key: CASSANDRA-11158
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11158
             Project: Cassandra
          Issue Type: Bug
          Components: Compaction, Local Write-Read Paths
            Reporter: Samu Kallio


We've been running Cassandra 3.0.2 for around a week now. Yesterday, we had a network event
that briefly isolated one node from others in a 3 node cluster. Since then, we've been seeing
a constant stream of "Finished hinted handoff" messages, as well as:
