    While running an application that reads data from Cassandra 2.1.0 using Java driver 2.1.2 or 2.1.3, the driver starts throwing the error messages shown below. There is no connectivity issue since the driver is able to connect and read data when the application is launched. These error messages are logged after the application has been running for some time. {noformat} 21:15:59 WARN c.d.d.c.Connection Forcing termination of Connection[hostname/ip:9042-1, inFlight=5, closed=true].
