Suspicious DNS Activity Originating from GTM Name Server

Hi All,

 

We are seeing continuous TCP packet reset error at client side from 3DNS name server. Search on GTM log & taken packet capture but no clue where rest packet is generating. From searching Google for similar issues, this seems to be related to an outdated/mis-configured Bind DNS server. Need your suggestion to close case.
