Anomalies:

DOY 058 (02/27/05) ACE Anomaly G05-0026  ROBOTT Color Allocation
ROBOTT/C&C has a known issue that if not enough display colors are
available, it may not start.  On Friday (02/25/05), not all displays were
closed before the weekend.  C&C did initialize successfully on Saturday, but
required 2 attempts before successfully starting on the 3rd attempt.  If the
3rd attempt had failed, a failover to the backup string would have occurred.
IMPACT:  Minimal.  RTMon restarted C&C but resulted in AR G05-0029.


DOY 059 (02/28/05) ACE Anomaly G05-0029  2nd Instance of ROBOTT/C&C Started
The color allocation dialog box was present after Sunday's restarts.
Acknowledging the dialog box resulted in a second instance of ROBOTT/C&C
starting during Monday's pass.
IMPACT:  Minimal.  FOT was able to properly terminate the 2nd instance of
C&C.


DOY 059 (02/28/05) ACE Anomaly G05-0027  MAD 26m (DSS-66) Late Acquisition
Station had difficulties acquiring lock at AOS.  DR#M103087
IMPACT:  Activities delayed 11 minutes.


DOY 059 (02/28/05) ACE Anomaly G05-0028  No Notification of TLM Loss
ROBOTT/C&C has a known issue that if telemetry is briefly online, ROBOTT/C&C
may not send notification that TLM is no longer available (CDSID#00021110).
IMPACT:  Minimal.  FOT was already on console trouble-shooting other
problems and noticed that TLM was not available at BOT.


DOY 059 (02/28/05) ACE Anomaly G05-0030  MAD 26m (DSS-66) RNS Problems
Problems with the D66's Reliable Network Server (RNS) resulted in several
intermittent TLM outages throughout the support.  DR#M103089
IMPACT:  Minimal.  All data was available on CDR.


DOY 059 (02/28/05) ACE Anomaly G05-0031  ROBOTT/C&C Restart
C&C is designed to set an alarm when a procedure has been at the same line
for more than 5 minutes.  This alarm flagged during an large SSR redump.
The alarm was cleared and C&C was restarted for unknown reasons.  The redump
procedure was restarted by C&C.  Developers have been notified of the
problem.
IMPACT:  Minimal.  Redump procedure had been recently updated in case of
multiple executions.
