It seems to be load and configuration dependant as I've never seen it
on my machines. It would help if problem were reproducable and problem
machine were easily accessible.

I looked (and in linux too), we diverged with OpenBSD quite a bit due to our SA,
FreeBSD was originated from BSDI core with our drivers so is quite different from
the beginning. You won't find a fix for the problem comparing sources.
