+
+	* tao/Synch_Invocation.cpp (handle_system_exception):
+
+	  Corrected repository IDs for non-fatal system exceptions being
+	  detected (TRANSIENT, OBJ_ADAPTER, NO_RESPONSE).  The
+	  "IDL:omg.org/CORBA/" prefix and ":1.0" suffix were missing, thus
+	  preventing code that should have been run in the presence of
+	  these exceptions from being run.
+
+	  Attempt to try another profile in the non-fatal exception case.
+	  This fixes a problem where valid profiles were not retried when
+	  they should have been.
+
+	* orbsvcs/orbsvcs/LoadBalancing/LB_LeastLoaded.h
+	  (LL_DEFAULT_LOAD_PERCENT_DIFF_CUTOFF):
+
+	  New constant used in thundering herd fix described below.
+
+	* orbsvcs/orbsvcs/LoadBalancing/LB_LeastLoaded.cpp (get_location):
+
+	  Fixed problem where least loaded object group member was not
+	  always selected, thus reducing scalability.
+
+	  If two locations have loads that differ by a "small" amount
+	  (i.e. LL_DEFAULT_LOAD_PERCENT_DIFF_CUTOFF), choose one of them
+	  at random.  This helps alleviate a thundering herd phenomenon
+	  that could occur when an object group member becomes available
+	  for request handling.  Thanks to Carlos, Marina and Jody at ATD
+	  for coming up with this solution to this form of the thundering
+	  herd problem.
+
+	* orbsvcs/orbsvcs/LoadBalancing/LB_ServerRequestInterceptor.cpp
+	  (receive_request_service_contexts):
+
+	  Always allow LoadMonitor and LoadAlert operations to proceed
+	  regardless of the alert condition.  Addresses a problem where it
+	  was not possible to disable alert states and query loads from a
+	  LoadMonitor collocated with a server once a load alert was
+	  enabled.
+
+	* orbsvcs/performance-tests/LoadBalancing/ORBInitializer.h:
+
+	  Improved documentation of some class members.
+	
+	* orbsvcs/performance-tests/LoadBalancing/ORBInitializer.cpp:
+
+	  Cosmetic change.
+
+	* orbsvcs/performance-tests/LoadBalancing/RPS_Monitor.cpp (loads):
+
+	  If the elapsed-time is zero, set the load to zero to prevent a
+	  division-by-zero error.
+
+	* orbsvcs/performance-tests/LoadBalancing/Roundtrip.cpp
+	  (test_method):
+
+	  Commented out a bunch of code that should not be used when
+	  performing benchmarks.
