OOME at slave during replication
--------------------------------

                 Key: DERBY-3497
                 URL: https://issues.apache.org/jira/browse/DERBY-3497
             Project: Derby
          Issue Type: Bug
         Environment: trunk at revision 633807
            Reporter: Øystein Grøvlen


After deleting and inserting more than 1 million records during replication, I got 
java.lang.OutOfMemoryError: Java heap space.

The heap dump shows that almost the entire heap is byte arrays, and it seems most of them
are referred to by ReplicationMessage objects.  An inspection of the heap dump in VisualVM
it seems that it is references rooted in SocketConnection#objInputStream that keeps them from
being garbage collected.
