Hello Murthy, I think that the problem with VPP 20.05 that I wrote about back in October 2020 later turned out to be related to NAT44 hairpinning, see the discussion here: https://lists.fd.io/g/vpp-dev/topic/78662322
A fix was merged so the exact same problem should not happen for the 21.06 version that you are using. If you have some similar problem in the sense that VPP runs out of memory for some unknown reason, then my advice would be to gather as much statistics as you can (error counters and so on) from around the time the problem happens, to see if that gives you any clue.
