Subject Re: index corruption with latest lucene
Date Tue, 06 May 2008 09:30:11 GMT

Could you provide more detail on how you hit these two exceptions?   
Are they reproducible from scratch (creating a new index)?

Are you using multiple threads against IndexWriter?  Is autoCommit  
true or false?  Any prior exceptions hit?  Do your documents have  
varying number/configuration of fields?  Is the index copied  
somewhere after being written?

Can you run with assertions enabled to see if something is tripped?

Maybe run CheckIndex on the index?
