When I try to rebuild a big file (2 segment: NCAUNITA and NCAUNITA.^01) the utility rbldcli.exe freeze creating the indexes

The original file have more than 4.500.000 records and 6 segmented keys and rebuilding the indexes (sometimes at first index, other times at other indexes) w3dbsmgr.exe use the 99% of CPU but don't wrote anythings on the disk

The version is 10.10.063 

Exists a new version of Beta to test ?

Building the index, especially if there is sufficient RAM to build it in memory, can take a VERY long time.  If the data records fit in cache, then the system will NOT write anything out to disk until the entire index build process completes, so your symptoms could certainly be just normal operation.

The times are usually exponential in relation to the file size.  Are you sure that it is really stuck, or do you just have to wait longer?
