Not quite - the size of the data segment is limited to the value of 'limits -d', which starts out at DFLDSIZ and cannot be larger than MAXDSIZ. Likewise, the size of the stack is limited to the value of 'limits -s', which cannot be larger that MAXSSIZ. I don't think there's a limit on text size (other than "total address space minus kernel address space"), but a very large text segment will obviously limit the size of the data and stack segments. > You can raise this up to 2GB or > so, but you will eventually hit the KVM boundary.

The kernel address space used to be 256 MB in 3.x, but was bumped to 1 GB before 4.0-RELEASE. See FAQ list entry 17.15.
