>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10861
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Streaming and Messaging
>         Environment: Ubuntu 14.04.3 LTS 64 bits, Java build 1.8.0_66-b17, tomcat 8.0.23
>            Reporter: Carlos Scheidecker
>             Fix For: 3.0.1
>
>         Attachments: error_log_tomcat.txt

>
> Same dev environment with same application on Tomcat 8.0.23. However the dev nodes have
been upgraded to 3.0.0 and later to 3.0.1. The Cassandra driver is version 3.0.0-beta1.
> It seems that connections crash, do not get cleared and it leads to a memory leak stack
overflow condition.
> Attached is an error log file from tomcat.
