Hi,

I'm getting intermittent infamous errors:

Class: com.romeblack.release.core.EntityHomeException: An I/O error
occured while sending to the backend.
Exception: java.net.SocketException: Socket closed
Stack Trace:
java.net.SocketException: Socket closed

at
org.postgresql.jdbc2.AbstractJdbc2Statement.execut e(AbstractJdbc2Statement.java:389)

These errors don't always occur - sometimes I'm able to run and test the
entire application without ever running into them.

I'm using Tomcat 5.5.9 and JDBC 2 driver 8.0-312 connecting to an 8.0.3
database on Fedora 4.

What can I do to fix this problem?

Thanks,
Simon

This means you're trying to use a Connection that has had close() called
on it, or that has encountered a fatal I/O error previously (this would
have been reported via throwing an appropriate SQLException) that you
ignored.

I guess you are using connection pooling then; I'd suspect some problem
there.
