request platform software trace archive last 2 days 

Run the command above.  
It will manually generate a tracelog file and will be found in the flash-1: folder.  

Upload this file to TAC and get them to analyze it.

Thanks Leo. I will check with TAC accordingly

 - You may want to try 16.9.5 which is current advisory release for this platform. Check if the problem persists afterwards.
