Well not software, this is hardware but last week there was a 2mm leak in the ISS (one of the greatest engineering achievements of mankind, with lots of software in it as you might imagine). This stresses the importance of traceability (to resources):

There's a person who drilled the capsule wrongly and did not report it. Fixed with... Glue.
Quoting:
"“We are able to narrow down the cause to a technological mistake of a technician. We can see the mark where the drill bit slid along the surface of the hull,” Dmitry Rogozin, head of the Russian space agency Roscosmos, told RIA Novosti. (A translation of the Russian articles in this story was provided to Ars by Robinson Mitchell). “We want to find out the full name of who is at fault—and we will.”"
