Hello, Current latest Cassandra version (3.11.0, possibly also 3.0.12+) has a race condition that causes Cassandra to create broken sstables (stats file in sstables to be precise).
Bug described here: https://issues.apache.org/jira/browse/CASSANDRA-13752 This change might be causing it (but not sure): https://issues.apache.org/jira/browse/CASSANDRA-13038 Other related issues: https://issues.apache.org/jira/browse/CASSANDRA-13718 https://issues.apache.org/jira/browse/CASSANDRA-13756 I would not recommend using 3.11.0 nor upgrading to 3.0.12 or higher before this is fixed. Cheers, Hannu
