Very few studies of software as it is and as it runs.
Try http://www.research.ibm.com/people/n/nickmitchell/publications/lcsd2005.pdf to a paper called "Diary of a Datum" and http://portal.acm.org/citation.cfm?id=1297046 to another paper called "The causes of bloat, the limits of health". Both describe studies of large running applications in situ.
Full disclosure - I work for IBM Research and these papers were by folks in my department.
