Symptoms

When reproducing the failover scenario for a client, of killing a operating system process for an established connection, Transparent Application Failover (TAF) reports ORA-3113: end-of-file on communication channel or ORA-3135: connection lost contact. But the connection does failover.

Other failover scenarios, Instance or Node down work fine.
