I am using Oracle Application Server and PostgreSQL for my application.
When i am calling a procedure it gives me following error. But this happens sometimes not frequently.

I am not able to find out what exactly the problem is.

Code:

org.postgresql.util.PSQLException: An I/O error occured while sending to the backend.
Exception: java.io.IOException: Stream closed
