> Running Jetty within the example folder seems to work normally, but not
> within the multiprocess-example folder. In both configurations I have defined
> a Solr Output Connector and a web crawler. The funny thing within the latter
> folder is that nothing is sent to Solr. The crawler just fetches and fetches,
> and that is the only activity I can see.
> I have ran:
> ./start-database.sh
> ./initialize.sh
> ./start-agents.sh
> ./start-webapps.sh
> The Solr Output connection is working and I have gone through the settings in
> my job - very similar configurations from my first attempt within the example
> folder, but nothing shows up.
> When I looked in my logs, I discovered this:
