   -- 13 DR fixes in this release.
         --- 12 DRs have been verified by the FOT to date.
           ---  The last DR to be verified will require ROBOTT to be 
observed over a period

Anomalies:

DOY 04289 (10/15/04) ACE Anomaly G04-0088 (Appended) - ADS Failure
FDF received the recurring GenSAA error message (The GenSAA IEP Server 
listen on port 2218 failed because System Error:  Address already in use.") 
when they attempted to start ADS today.   FDF acknowledged pop-up box and 
continued with task.  This is the tenth documented instance since early 
August.   IMPACT:  None.

DOY 04290 (10/16/04)  ACE Anomaly G04-0120 - GDS 34m (DSS-27) SCP Swap
DSS-27 requested authorization to swap SCP's.  However, during the swap, 
telemetry went offline for 26 seconds.  IMPACT:  None.  Telemetry recovered 
from SSR.  DR#G10488

DOY 04294 (10/20/04)  ACE Anomaly G04-0121 - GDS 26m (DSS-16) Antenna RED
At 15:40  OPS Chief called FOT to notify them that DSS-16 was RED because 
of antenna hydraulic problems.  FOT attempted to reschedule with DSS-24 but 
were unable to due to DSS-24 being down for maintenance.  Additional time 
was scheduled for next day's pass to allow dumping of 
recorders.  IMPACT:  Lost support.  DR# G104901
