Are you sure there was no OutOfMemoryError thrown within the JDBC driver 
code? (perhaps caused by some other part of the application exhausting 
the heap?) The driver isn't very good about keeping connections in a 
consistent state when unexpected exceptions are thrown. One possibility 
is that OOME was thrown partway through reading or writing a message on 
the protocol stream, but the driver did not invalidate that connection. 
Subsequent use of the connection will then fail randomly since the 
driver is out of sync with the message boundaries the server is expecting.
