Bartłomiej Romański created CASSANDRA-4639: ----------------------------------------------
Summary: Incorrect counter values Key: CASSANDRA-4639 URL: https://issues.apache.org/jira/browse/CASSANDRA-4639 Project: Cassandra Issue Type: Bug Components: Core Affects Versions: 1.1.2 Environment: We've got a production 21 node cluster with 3 virtual data centers. Keyspace that contains counter column families has a replication 3 on DC1 and 1 on DC3. DC1 is using SSD drives, DC3 spinning hard drives. We are using Ubuntu Server as an OS. Machines have 24GB of RAM. Reporter: Bartłomiej Romański Priority: Critical Since yesterday almost all counters are incorrect. Usually about 4-5 times higher than expected. In logs we've got this message: ERROR [MutationStage:15] 2012-09-10 13:47:13,280 CounterContext.java (line 381) invalid counter shard detected; (6de8e940-dd23-11e1-0000-5233df6faaff, 7, 242) and (6de8e940-dd23-11e1-0000-5233df6faaff, 7, 392) differ only in count; will pick highest to self-heal; this indicates a bug or corruption generated a bad counter shard every couple of seconds. This cluster was running without any serious problems for at least 2 months. Any ideas? -- This message is automatically generated by JIRA.
