Perl's garbage collector counts references. When the count reaches zero (which means that no one has a reference), Perl reclaims the entity. The approach is simple and effective. However, circular references (when object A has a reference to object B, and object B has a reference to object A) present a problem. Even if nothing else in the program has a reference to either A or B, the reference count can never reach zero. Objects A and B do not get destroyed. If the code creates them again and again (perhaps in a loop), you get a memory leak. The amount of memory allocated by the program increases without a sensible reason and can never decrease. This effect may be acceptable for simple run-and-exit scripts, but it's not acceptable for programs running 24x365, such as in a mod_perl or FastCGI environment or as standalone servers.
