Kibana 4 Process Crash

Hello everyone
I have a problem with Kibana 4, every moorning I open my browser on kibana page and I received the message "Waiting for elasticsearch is loading messages", the page don't get results, If I refresh the page Kibana Process go down.

I had the following configuration on 2 servers:

  • 1 with Logstash that send data to elasticsearch 1.5.0
  • 1 with Elasticsearch 1.5.0 and Kibana 4.0.2

Running on RHEL 5.5 x64.

Kibana does not log anything.

Could anyone help me?
Thanks in advance.

This moorning I opened kibana web interface and I received the following error:
Kibana is loading. Give me a moment here. I'm loading a whole bunch of code. Don't worry, all this good stuff will be cached up for next time!

After that Kibana Process ha goes down, after process restart kibana goes up and all data is correct on elasticsearch.
Elasticsearch log is fine.
