Re: DataSource suddenly drops all connections?

You wouldn't have happened to get any "Broken pipe"
errors like the following, because I am having a
problem with this and cannot figure out what is
causing it?

java.sql.SQLException: IOError while reading from
backend:
java.net.SocketException: Broken pipe
at
postgresql.PG_Stream.ReceiveChar(PG_Stream.java:183)
at
postgresql.Connection.ExecSQL(Connection.java:668)
at
postgresql.Connection.setAutoCommit(Connection.java:377)
