Getting RuntimeException: after flush: fdx size mismatch while Indexing

[Jamir Shaikh]

I am using Lucene 3.5. I want to create around 30 million documents.
While doing Indexing I am getting the following Exception:

Caused by: java.lang.RuntimeException: after flush: fdx size mismatch: 7442
docs vs 32768 length in bytes of _ct.fdx file exists?=true

                ... 10 more


I don't get this Exception consistently.

I am not setting the maxBufferedDocs the default value is -1.

So the flush is as per ramBufferSizeMB which is set to default 16.0 MB.


Did anyone face this problem.

I would appreciate any suggestions.
