Hi All,

I am trying to merge different indexes into one index
and I get following excpetion. The program I used to
merge the indexes is at the end of the email.

When I list the segmentnames in the segments files in
the corresponding index directory I see the particular
segment (_87aa) in the index but no files associated
with the index. I have no idea what happened.

I did try to merge this index with others onece beofre
and it successfully completed. But its failing now.
More interestingly it fails while optimizing ( I had
print line is optimize call ).

Looks like there is some problem with remerging the
index which has already been merged before.
Theoretically it shoudln't be the problem becuase
merge program is just reading the index and writing a
new merged one . Any help will be appreciated.

Thanks
Rajive
