Hello, We run Cassandra 2.1.13 and since last few days we're seeing below in logs occasionally. The node then becomes unresponsive to cqlsh.
ERROR [SharedPool-Worker-2] 2017-11-08 17:02:32,362 CommitLogSegment.java:441 - Attempted to write commit log entry for unrecognized column family: 2854d160-3a2f-11e6-925c-b143135bdc80 https://github.com/mariusae/cassandra/blob/master/src/java/org/apache/cassandra/db/commitlog/CommitLogSegment.java#L95 The column family has heavy writes, but it hasn't changed schema / load wise recently. How can this be troubleshooted / fixed ? Thanks !
