java.net.ConnectException: Connection refused

After starting use of this module we are seeing alot of java / kafka errors from linkerd.

java.net.ConnectException: Connection refused

Where Collector-Domain.com points at an AWS NLB and targets are jaeger-collector containers running in ECS.

This issue happens intermittently on hosts and seems to only be solved by a restart of linkerd. Any insight would be appreciated.
