I tried with ulimit -d 2097152, but when I check back again (immediately after setting it), it reads "data seg size           (kbytes, -d) 524288" (again).  I tried changing kern.maxdsiz, but I get "sysctl: unknown oid 'kern.maxdsiz'"... I'm running 6-STABLE as of two days ago.

Good day

try in kernel config something
options         MAXDSIZ=(1024UL*1024*1024)
MAXDSIZ constant is hard encoded into kernel
