v0.16.1
Disable keep alive forces the HTTP client to drop the connection once a response is received. This avoids building up large numbers of idle connections and it fixes the immediate issue. After this we may want to see how to ensure we can re-use connection and also set and idle-connection timeout. Fixes #3190 (cherry picked from commit 7a9a85b4a6343056902f90d3e3b34e8eac3c1fb2)
