You cannot address more than 4 GB on a 32-bit machine because 4 GB = 2^32.
In practice the amount of usable memory is even lower because the OS also
occupies some. So there is no way to make full use of the 16 GB you have
without upgrading the machine to 64-bit.

Thank you very much for the information. The machine is 32-bit but the main
memory is 16GB. The system contains: 2 Intel(R) Xeon(R) CPU X5365 @
3.00GHz (2 Quad-core processors).

The size of the data structures are fine, the issue is that you run out of
memory on your machine. Are you running dedup on a 32-bit machine? Or do you
maybe have only 4GB or less of memory installed?
Unfortunately there's little you can do about that error. It is a
memory-intensive program. We're working on a new version which should be
more economical, but it'll be a while until it's ready.

I am getting the following error when I try to execute dedup with native
input. Please let me know what to do to execute it without any errors. I
guess that somewhere I need to increase size of some data structure. Please
let me know which one.
