Your elasticsearch is not starting, there is something wrong and you need to check on the system logs, `/var/log/messages` or `/var/log/syslog`.

This is expected, your Elasticsearch is not running, so Kibana can not talk to it.

I would check the elasticsearch.yml if there is enough resources (CPU, memory etc.) allocated for elasticsearch. Your logs say that you have memory / performance issues.
