metrics not properly send when restart oc-agent

[yiyijin]

we are using oc-agent version as below, and we are running oc-agent on kubernetes environment.

omnition/opencensus-agent:0.1.6
and a problem noticed is, even when the pod is killed (so no more metrics sent by this pod), the oc-agent still keeps the old metrics, and prometheus is still getting the old metrics from oc-agent.

It looks like restart oc-agent pod fixed the issue, however there is another problem I have seen:
when oc-agent pods restarted, it seems the pods that are sending metrics to oc-agent, oc-agent is not getting all the data.

I just wonder is there anything I might have missed? Thanks a lot!
