It's probably not a problem with garbage collecting as such, but
rather that you don't have any.  In other words, your program is
retaining too much data.  Often, this is caused by too much (or
sometimes too little) laziness.

I haven't used Hugs for a while, but with GHC there is heap profiling.

The GHC docs describe this fairly well, I think, see:
  http://www.haskell.org/ghc/docs/latest/html/users_guide/prof-heap.html
