runs continuously for 6-7 hrs with index size reaching around 7-8GB. To reproduce the corruptions
sooner, I have placed the merge ( maybemerge ) call immediately after addIndex is called.
We have a final index which is in the mounted drive, we always add documents to an local intermediate
index and then call add index and merge to the final index.
