MySQL java.net.SocketException: Broken pipe

Hi,

I have a MySQL server and client running at the same server. However, when running long times ~few hrs, it will come out some Exception as following :
21:54:34,438 ERROR [SpDataSource] com.mysql.jdbc.CommunicationsException: Commun
ications link failure due to underlying exception:

** BEGIN NESTED EXCEPTION **

java.net.SocketException
MESSAGE: Broken pipe

STACKTRACE:

at com.mysql.jdbc.PreparedStatement.executeQuery(PreparedStatement.java:
1024)
** END NESTED EXCEPTION **
Last packet sent to the server was 1 ms ago.

This kind of error came out in random. As I run the client and server at same host(localhost in driver setting) so it should not have network problem cause broken pipe. The MySQL version I use is 4.1.8 and JDBC Driver is 3.1.10. The socketTimeout of the driver has been set to"0". I use connection pool so that every connection is reused but not "new" on demand.

Please help to advise what's wrong.
