I see just what it sounded like: httpd tries to mmap a much larger file
than it actually has:
1878 27 httpd CALL __stat50(0x7f7ff7bb16f0,0x7f7fecbff780)

Ie httpd tries to mmap 2K:
1878 27 httpd CALL mmap(0,0x800,1,1,8,0,0)

Hmmm. This is apache-2.4.16 from NetBSD pkgsrc; I've tried both a
binary package provided by NetBSD as well as a locally compiled pkgsrc
version.
Next up: manually compiling vanilla httpd, I suppose. :-/
