Recently got this following error in my application JPA/Hibernate with database Oracle RAC 11g.
This error occurred when our storage was full and DBA needed close connections, kill active sessions, or some like this "Connection closed" (now I can know what happened, he was fired....)

Talking with other DBA he said that one instance from Oracle got full disk, and the registers partial commiteds was created in this moment, but he just deleted trace files, didn't stop db and not killed any session.
