I would suggest tying the big complex hash to DBM::Deep before creating the big complex data structure. That is because processing the whole thing at once takes up too much memory. Doing it incrementally from the start will behave much better.

If that fails then try to come up with a minimal test case and file a bug report at http://groups.google.com/group/DBM-Deep?pli=1.
