Subject shutdown Observer
Date Thu, 09 Mar 2017 17:00:47 GMT
Hi,

We have a multi data-center zk cluster with all the followers are in one
data-center and observers in other data-centers, for some reason observers
are going down with the following exception and i am not sure what could be
the reason and how to avoid this issue, any thoughts?

Ram
