I believe OpenBSD ships with strict limits on memory that a process can allocate, perhaps you’re bumping into them?

You can check amount of memory allowed with:

$ ulimit -d

(the output is in kilobytes)

Unfortunately, I’m not familiar with OpenBSD enough to know how to reconfigure the limits, but I think it’s done in /etc/login.conf:
