As far as I know, projwfc.x does not need more memory than a scf or nscf calculation (It should actually take somewhat less). In a similar recent case, neither I nor other people in Cineca found any evidence of memory leaks or sources of unexpected memory usage. WIthout more information, it is hard to say more (and even with more information: large jobs are not easy to debug)
