   Hi,
   Samba/CIFS is generally working as file store - in contrast to NFS, which should never ever be used as file system; but the problems you describe here are surely related to problems with a shared file system. Whenever possible please make the store a local disk, don't use shared/network filesystems to store Lucene indexes. We can't give you any recommendations here, there are surely no known bugs in Lucene that could create above index corrumption.
   
   In short: please avoid NFS (under all circumstances) and avoid CIFS (where possible, especially under high load). Shared/network file systems should only be use for read-only indexes.
   
   Related question: we are wondering why you not use MMapDircetory but instead use NIOFSDirectory?
