java.lang.IllegalStateException: Index has been shut down

[Peter Ehrlich]

After redploying to trinidad/tomcat, I got the following index illegal state error, which crashed the entire application and required a hard reboot to remedy (now its working without error).  Can anyone tell what could cause this, or how to fix/prevent?  I'm running 1.7M01.

Seems identical to this issue here:

Thanks!

Peter,
this looks like if Lucene has been shut down somehow. Got a
messages.log on this?

Ah, thanks for asking! I'll watch this file in the future.

Here's logs from that issue:

This is about as interesting as it gets:

and so on..

Ok,
let us know if there is anything popping up again.

It may be that your application or library is holding on to an Index reference and tries to use it after the database has been restarted.

Interesting.  Would that be a bug?

It would seem strange, as it appears that the app and db get restarted as one.

Hi all,

Same here.

I'm using Neo4j in HA mode with Rails. I'm connected to master from app and to one of the slaves from console. After updating a record I got exactly the same error. The property I updated had an index on itself. It seems that Lucene doesn't play nice when in HA mode, or something. Is it a bug?
