Kibana 4 appears to break if using scripted fields and deleting old logstash indices

[silverl]

Using Kibana 4 RC1 and ES 1.4.3.

I purge logstash indices nightly to maintain a rolling 90-day window of log data.

I created some visualizations and dashboards against my logstash indexes using the basic index pattern [logstash-]YYYY.MM.DD.

I added scripted fields like:
bytestotal = doc["bytesin"].value + doc["bytesout"].value
@timestamp._hourOfDay Integer.parseInt(new Date(doc["@timestamp"].value).format("H")) number

Everything works fine for that day. The next day, Kibana 4 is throwing errors on the Discover tab and nothing works. Overnight, the oldest index was intentionally deleted by cron.

If I then delete all my scripted fields, Kibana 4 starts working again. I can re-add them, continue on my merry way.

I couldn't find any errors in the node service logs. Couldn't figure out how to extract a meaningful error from the K4 UI.

It look like you're using scripts from Beta 3. RC1 and above do not support Groovy scripting due to this ticket: #9655

Can you tell me how you arrived at the conclusion that this is due to scripts from Beta 3?

Closing this ticket as this is not an Elasticsearch issue.
