Name and version of the database you are using: MySql 5.0

We have hibernate search setup on a JBOSS cluster using MDB. I am getting the above exception in some interval of time. Also I get a warning saying unable to remove previous marker from file. Are these pointing to some configuration issues and something is not happening properly?

I would apreciate if you could give:
- the exact HSearch version
- the exact Lucene version
- the JVM version and vendor
- the OS you are deploying on

Also, can you describe your architecture (ie deployment, directories) and the HSearch configuration file.

When you say some interval of time, do you mean it come and go from time to time without touching anything?
