Hi Karl,

Crash here means, "the site could not be reached" kind of HTML page appears
, when accessing http://localhost:3000/mcf-crawler-ui/index.jsp.
Explanation:- When running certain job on ManifoldCF server(2.13) after
sometime (of successful running state), suddenly browser gives me "the site
could not be reached" (this kind of error) and page does not reload until i
restart it through docker command.
once i will restart the container through docker MCF get to load again.
