DOY 076  03/17/2010  S-WIND-0392          ITOS tm_controller
Before Beginning Of Track, ITOS had problems connecting telemetry,
"timeout reading from tm_controller".  ITOS was stopped and restarted
and the WIND pass was taken successfully.  This appears to be the same
problem that occurred on 03/06/2010 (DOY 065 S-ACE-0491 G10-0014).  DR
CDSID#00027515 has been submitted for ITOS developers.
IMPACT:  Manual intervention required.


DOY 077  03/18/2010  S-ACE-0493  G10-0016 Problems with JPL ERNS
Problems with the JPL Enhanced Reliable Network Server (ERNS) caused
brief network outages (1843z and 1847-1850z).
IMPACT:  Minimal.
