-----------------------------------------
Attachment: 8285.txt
> OOME in Cassandra 2.0.11
> ------------------------
>
> Key: CASSANDRA-8285
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8285
> Project: Cassandra
> Issue Type: Bug
> Environment: Cassandra 2.0.11 + java-driver 2.0.8-SNAPSHOT
> Cassandra 2.0.11 + ruby-driver 1.0-beta
> Reporter: Pierre Laporte
> Assignee: Aleksey Yeschenko
> Attachments: 8285.txt, OOME_node_system.log, gc-1416849312.log.gz, gc.log.gz, heap-usage-after-gc-zoom.png, heap-usage-after-gc.png, system.log.gz
>
>
> We ran drivers 3-days endurance tests against Cassandra 2.0.11 and C* crashed with an OOME. This happened both with ruby-driver 1.0-beta and java-driver 2.0.8-snapshot.
> Attached are :
> | OOME_node_system.log | The system.log of one Cassandra node that crashed |
> | gc.log.gz | The GC log on the same node |
> | heap-usage-after-gc.png | The heap occupancy evolution after every GC cycle |
> | heap-usage-after-gc-zoom.png | A focus on when things start to go wrong |
> Workload :
> Our test executes 5 CQL statements (select, insert, select, delete, select) for a given unique id, during 3 days, using multiple threads. There is not change in the workload during the test.
> Symptoms :
> In the attached log, it seems something starts in Cassandra between 2014-11-06 10:29:22 and 2014-11-06 10:45:32. This causes an allocation that fills the heap. We eventually get stuck in a Full GC storm and get an OOME in the logs.
> I have run the java-driver tests against Cassandra 1.2.19 and 2.1.1. The error does not occur. It seems specific to 2.0.11.
