It is, AFAIK, a multi-threaded application. I don't have any information
on which

Nope, I haven't looked in strace at all. It's definitely making it to
user-space. The code in question is (abbreviated):

I am absolutely seeing it outside of strace. It is showing up as an errno

Ok, so somehow it is leaking. I have a system in the lab that is the same
hardware as production, but it currently has no, you know, hard drives in
it, so some assembly is required. I
