The resource limits on BSD are more limited than on Linux.
Look:

NetBSD: ulimit -a
-----------------
time(cpu-seconds)    unlimited
file(blocks)         unlimited
coredump(blocks)     unlimited
data(kbytes)         262144
stack(kbytes)        2048
lockedmem(kbytes)    1111329
memory(kbytes)       3333988
nofiles(descriptors) 64
processes            160
sbsize(bytes)        unlimited
-----------------

OpenBSD: ulimit -a
--------------------
time(cpu-seconds)    unlimited
