17:00 : Started settings.
17:25 : \'/data1/gtac/cmd/42_059/42_059_23Aug2022_1700_cmd.py\' command file started.
17:30 : TGC scripting server hung.
        Restarted command file.

17:40 to 17:50 : Scripting server hung, so Phasing took too much time (8 mins).
      : Observation session could not be completed due to multiple problems. band2 observation has not having clear phase visibility on 1822-096. phasing was not upto the mark. 
      : C04,C10  -- was having FECB related problem.
      : C05,S02  -- was having GAB configuration problem.
      : C09      -- Feed jam.
      : C03      -- Mechanical Work.
 Note : This observation may be considered for Makeup time.
17:55 : Stopped command file and observing session over.
