GIFT Indexing

Hi all,

I installed GIFT without any errors and it worked fine with a small image 
collection.

I have indexed 169,685 images with GIFT and it took nearly two weeks to 
complete it. I think this is the first ever attempt to index GIFT with a 
large collection :) My problem is that, the indexing process did complete, 
but there was no *.ADI file generated and the inverted files:
- InvertedFileFeatureDescription.db
- InvertedFile.db
- InvertedFileOffset.db

did not contain anything. Below is the last part of the indexing messages, 
and it seems that there was some failure:

My questions:
1) Is the failure caused by the collection size? - I assume no.
2) How can I resolve this problem.

Please shed some light. I really need your advice.

Thank you,
