    Resolution: Duplicate

> Cassandra 2.0.1 leaking open file handles for deleted system hints
> ------------------------------------------------------------------
>
>                 Key: CASSANDRA-6392
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6392
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Core
>         Environment: Cassandra 2.0.1
> Cassandra datastax java driver 1.0.3 (cassandra-driver-core)
>            Reporter: Prateek
>
> The system was running for a few days with a heavy write workload. The system 
> crashed with too many open file handles. It seems the deleted system hint 
> file handles are still open even though the file has been deleted on disk. We 
> use a 3-node cluster with replication factor 3 on ec2 us-east-1 using 
> NetworkTopologyStrategy. Default consistency level for write is ANY.
> This is blocking our production deployment and causing instability in 
> production. 
> Appreciate your quick response.
> Many thanks,
