In the interest of helping you get work done, it sounds like you're
running a task that has a (much?) larger resident set requirement than
this box has physical memory available to userspace, resulting in constant
paging that drags it into the bowels o
usr/libexec/ld.so, or build static executables with -static.
$ ld exit.o -o exit -static
$ ./exit
$
Note that by default OpenBSD marks executables as PIE (position
independent executable) which places constraints on how code generates and
uses addresses. You'll need to link with the -nopie option if you can't
meet that requirement.

That's an odd place to crash, having nothing to do with the filesystem
