[BUG] SIFT-1B Build Bug

[L4ai6l]

The above are the terminal interface when stopping and the command to build the index.
My question is "When I used build_disk_index in DiskANN to build the index file of SIFT-1B, the system was divided into 9 partitions because the file size exceeded the memory size (I used a 128GB memory machine). After building 5 partitions, it stopped running without any errors, and there was no kill information in the terminal. I would like to ask what caused this situation? Are there any parameters that need attention?
