Anomalies:

DOY 185  07/04/2009  S-ACE-0450  G09-0045  Network and Automation
Problems
The Goldstone Complex had a loss of all NTR Ckts due to a down OC192
line at the San Bernardino Central Office.  The network loss caused the
ACE MOC automation software (C&C/ROBOTT) to freeze.  The Real-Time
Monitor restarted C&C.  C&C started both SSR redumps and final
state-of-health checks at the same time.  Continued network data loss
resulted in slower procedure execution.  The spacecraft was returned to
a nominal state by EOT-3minutes.  DR#N105356
IMPACT:  All data was recorded by DSN's Central Data Recorder (CDR).
The CDR file was downloaded so that the automation software would not
spend 40 minutes redumping data on the following pass.

DOY 186  07/05/2009  S-ACE-0451  G09-0046  ROBOTT/C&C Start 2 Procs
ROBOTT/C&C started 2 procedures without waiting for the other to
complete; ULEIS_MOTOR_ERROR (20:10:12) and S_OPS_PLBK_COMPLETE
(20:10:13).  The procedure ULEIS_MOTOR_ERROR was paused while
S_OPS_PLBK_COMPLETE completed.  ROBOTT/C&C then terminated the
ULEIS_MOTOR_ERROR procedure.  CDSID#21085 & #21122
IMPACT:  The ULEIS_MOTOR_ERROR procedure does a daily check of the
status of the ULEIS shutter motor.  The shutter motor was nominal and
the procedure execution was not necessary.
