Intermittent I/O error? - Mailing list pgsql-jdbc

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 java.net.SocketInputStream.socketRead0(Native Method)
     at java.net.SocketInputStream.read(SocketInputStream.java:129)
     at java.io.BufferedInputStream.fill(BufferedInputStream.java:218)

org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:175)
     at
org.postgresql.jdbc2.AbstractJdbc2Statement.execute(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
