If the process was killed by OOM (out of memory daemon), then it cannot
print anything - it is simply stopped by the kernel.

But if it really fails with return code 3 (out of memory), then it should print
a visible error - if not, we have to fix it.
(Verbose option only translates return code to something readable but there should
be an error message much earlier.)

Is it simple cryptsetup open activation (no systemd-cryptsetup magic)?
(If so, please add new issue upstream and link this bug, we will fix that.)

Thanks,
