In addition to the excellent advice provided by others on this topic,
you may want to look at using GHC's heap profiler if you can't track
down the source of a memory issue.  I've found it helpful in the past.
 Keep in mind that there are several different modes that may or may
not be helpful for a particular problem, so you should try them all to
see if you get any useful information.
