What should be the problem?

Does r.topix crash, if yes, what it the error message, or does it just take
a long time to proceed after 74% have been reached?

The following information will also help to solve the problem:
What is the size of the input file in terms of rows and columns, what is
the current region, which operating system and how much free RAM on this
operating system?

Alternatively, you can also use the tci output of r.watershed.
