> Key: CASSANDRA-8210
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8210
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Environment: DSE 4.5.2, Cassandra 2.0.10, OEL 6.5, kernel
> 3.8.13-44.el6uek.x86_64, 128Gb of RAM, swap disabled, JRE 1.7.0_67-b01
> Reporter: Nikolai Grigoriev
> Priority: Minor
> Attachments: cassandra-env.sh, cassandra.yaml, occurence
> frequency.png, system.log.gz

>
> I have just got this problem on multiple nodes. Cassandra 2.0.10 (DSE 4.5.2).
> After looking through the history I have found that it was actually happening
> on all nodes since the start of large compaction process (I've loaded tons of
> data in the system and then turned off all load to let it compact the data).
