Øystein Grøvlen commented on DERBY-3064:

Thanks for the new patch Narayanan and for fixing all the minor nits I
pointed out.  I have some follow-up with respect to the initial

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
      derby.log very many times before the timeout occurs?  An
      alternative could be to link the last received IOExcpetion to
      the exception thrown when it times out.

MasterFactory:  Is SLAVE_DB a good name here?  It seems to me that we
are talking about the database at the master here.
