Problem Reports
PR NumberTimesTime LostDescriptionResponse
413900:53-01:0400:11Going to satellite after stacking always seems to fail on first attempt. Gives the usual "failed to acquire trajectory" error.
426201:30-02:5901:29Had a long string of PAS crashes of indeterminate origin. At first it seemed like running the DMI was causing it to crash, then maybe running TT pipeline. When it died one more time for seemingly no reason whatsoever, I called Randy and Jim and found out it was crashing because I was processing images in CWFS guider. No error message appeared to stop me from processing images in CWFS guider, so I assumed it was okay to do so. (Incidentally I forgot that I reported this problem earlier.)Called: Jim Fowler, Randy Bryant

428603:44-03:4600:02A trajectory unceremoniously aborted. Noticed the TCS light at top of TCS GUI was black; ran chksys and found the process listed as defunct.Shutdown/restart everything.
427506:06-06:0700:01The probe assembly tab was open and when RA made a probe move TCS GUI crashed. (It disappeared from Jove workspace and in jove terminal the process was listed as defunct.)
428808:05-08:1000:0508:05/50710: TMCS failed to acquire trajectory. Did not slew to start of track/new Traj Start Time didn't display in Tracker Monitoring tab on ControlDesk.Restarting everything led to same problem, then attempted the same trajectory again without restarting and it suddenly worked without any problems.
422605:00-05:0000:00HEFI still lost functionality tonight. Found a lot of orphaned HEFI processes when I ran a chksys command on jove.
428708:39-08:4200:0308:39/52750 PAS died again. (defunct) We were running closed loop on Guider 1 Camera.
