Bitnami ELK 6.5.x Not starting after installing RoR

Hi
Been using the Bitnami VM (azure) for about 12 month as its easy to setup and get running - but with 6.5.x, Kibana will not start up when trying to install RoR.

I originally thought the issues was related to the 6.5 issues that was common with 6.5.0, and 6.5.1. But even now I tried 6.5.4, and getting the same issue. When it is installing, the kibana log shows that its optimizing the cache, and a few hours later the command line comes back saying kibana could not be started. If i try to start kibana it fails after a few hours, with the same info in the log:

{“type”:“log”,"@timestamp":“2019-01-06T23:06:18Z”,“tags”:[“info”,“optimize”],“pid”:28016,“message”:“Optimizing and caching bundles for ml, stateSessionStorageRedirect, status_page, timelion, graph, monitoring, space_selector, dashboardViewer, apm, canvas, infra, readonlyrest_kbn and kibana. This may take a few minutes”}

Is anyone else using the Bitnami stack, and version 6.5.x?
