FYI: 

I do not have specifics any more, but I'll note that I've seen
such lsof behavior of failing at one time and later working
without any installed updates to it or the system between. I
rarely use lsof and, so, this was not recently.

I've no clue how to cause the failure(s) to show up. I've no
clue how common the issue is. But, over time, it is not just
you.
