Are you using each before this in your program? Are you calling the subroutine twice in a row without making changes to the HoH in between? If the while loop is preceded chronologically by another while loop with the same structure that might explain why the second loop is being skipped.

Data::Dumper probably resets the iterator and so it runs through the HoH normally. What happens if you change "print Dumper" to "keys"? Does it still cause the while loop to run?
