  1. Not able to get any clue from SUM log files .It was giving same error logs highlighted in SUM screen above.
  2. Check ST22 dump to get the clue of the issue .

In our case we were getting dumps related to“DATASET_CANT_CLOSE”. 

After checking dumps in details ,we came to know that there was an issue with SPACE in SUM directory file symptom.

3 . Added some extra space in the File System of SUM directory which fixed the issue and we moved further.
