@zachliu I was checking on this yesterday. Can you please try the below
patch? I tried the sample dag with a copy of 100 dags. The transport object
which is created per client could be causing the socket to be open is my
assumption as well. That's why this is prevalent in dags with connection,
variable etc. that triggers client creation and subsequently transport creation
which I feel could be cached.
