[error]: Unable to invoke action 'utils/echo' read: connection reset by peer

## Environment details:

ubuntu 18.04

When I finished deployment, I tried "wsk -d action invoke /whisk.system/utils/echo -p message hello --result"

The output is :
error: Unable to invoke action 'utils/echo': Post "http://172.17.0.1:10001/api/v1/namespaces/whisk.system/actions/utils/echo?blocking=true&result=true": read tcp 172.17.0.1:52650->172.17.0.1:10001: read: connection reset by peer
