>                 Key: SOLR-9539
>                 URL: https://issues.apache.org/jira/browse/SOLR-9539
>             Project: Solr
>          Issue Type: Bug
>          Components: Admin UI
>    Affects Versions: 6.2
>            Reporter: Mikhail Khludnev
>            Priority: Major
>              Labels: admin-interface, newdev, ui
>
> # Download Solr 6.2 and Zookeeper 3.4.6 
> # Launch Zookeeper {{$zkServer}}
> # Launch two Solrs {{$bin\solr start -z localhost:2181 -e cloud}}
> # stop Zookeeper 
> # get to new Admin UI. It's frozen. Respond with placeholders after few minutes. However, solr urls respond well.
> # launch Zookeeper back, UI respond smoothly and rapidly.
> I briefly checked chrome debug, I saw that every ...js response is slow, something like request filter might check zookeeper with timeout, but I don't know.
