Dear Questions:
I have a machine with 2G of ram. I would like to be able to malloc about
half of it. However I keep running into the max data segment size
limitation:
$ ulimit -d
524288
Is there any way to increase or amend this ?
I am running FreeBSD 4.9 RELEASE i386 with the following non
I should have mentioned that I built the kernel when the machine had
either 512M or 1G of ram, and have subsequently added another 1G. Would
rebuilding the kernel result in this limit being recalculated?

Bit sad replying to myself again:-)
Anyway - no it does not... still 512M
A bit of grepping through the 4.9 source finds that the beast
controlling all this is:
$ grep MAXDSIZ /usr/src/sys/i386/include/vmparam.h
#ifndef MAXDSIZ
#define MAXDSIZ (512UL*1024*1024) /* max data
Yes there is, some more poking around in /usr/src/sys/kern/subr_param.c
brought to light :
maxdsiz = MAXDSIZ;
TUNABLE_QUAD_FETCH(kern.maxdsiz, maxdsiz);
which looked suspicously like a kernel tunable for data segment size.
So setting kern.maxdsiz in /etc/loader.conf seems to be the thing
I mean in /boot/loader.conf (growl...)
