Hi,
I’m using PostgresSQL 7.4.7, pg74.215.jdbc3.jar in a computer which has Debian GNU/Linux 3.1. Sometimes, when the database’s connection is going to close I get the next PSQLException:
org.postgresql.util.PSQLException: An I/O error has occured while flushing the output - Exception: java.net.SocketException:
Socket closed
Stack Trace:
java.net.SocketException: Socket closed

I have catch this exception and I have got…
PSQLException's error code: 0
PSQLException's cause: null
PSQLException's sql state: 08S01
The PSQLException’s sql state tell me about COMMUNICATION ERROR but PSQLException’s error code tell me about Successful Completion. I dont know whether there is an error. I am confuse.
Does anyone explain me why happen this?
Thanks in advance.
