That error from bind,

Is not handled gracefully in the bsdstats script.

The annoyance is that ISC Bind finds it not useful to print errno, which is 
what you'd need to figure out why this lock can't be destroyed. It is however 
a programming error in bind, or a rare case of stack corruption by the kernel.

If you see this error a lot or can reliably reproduce it, I'd file a PR.
