V.Narayanan updated DERBY-3064:

    Attachment: LogShipperIntegration_v5.stat

>9. a) Will a timeout at this level work? As far as I can tell you
>      have not set any timeout on the socket. Is there a default
>      timeout, or do you risk that getting the connection may hang for
>      much longer than the desired timeout?

>   b) Don't you risk that the same error message may be written to

I have changed the patch to use socket timeout. I have removed the earlier timeouts used at
this level. IOExceptions are now being thrown, since overshooting the time interval would
throw a SocketTimeoutException rather than a IOException.

Changed it to MASTER_DB
