High throttle count on interface

Hi,

 

 I am seeing high throttle count on my router interface facing the ISP router. I read online and understood that it could be due to us switching to NVI NAT instead of classic NAT.

 

Is there a way I can troubleshoot this and bring the count to 0? Put in the outputs for 'sh run int g0/1' and 'sh buffers'
