Hmm. Are you certain:
12-sec# dd if=/dev/zero of=/var/cache/bar bs=1024k count=64
64+0 records in
64+0 records out
67108864 bytes transferred in 18.790176 secs (3571487 bytes/sec)
13-sec# ls -l /var/cache/bar

Hi, Duncan,
Thanks for your help!

Yes, 2G - 1 is the maximum size a signed int can hold ... mind you, any
program needing more that 2G of memory really should be implementing
on-disk storage of data for itself.
Thanks for your suggestion. In this case I
Thanks for all of your replies,
Now I can do it through recompiling the kernel and the limits did increase.
I haven't tried whether it can increase over 2G (I would love that if it
can!). The code I used cannot be easily changed to reduce memory
consumption but I think 2G would probably be en

Thanks, Chuck,
Which file should I put in the following ?

32-bit systems implementing VM typically could increase user-mode address
space up to 2 GB, although variants on that and other things (ie, where
devices get mapped into memory) make that only an approximation. For
FreeBSD:

This shows that you have much more than 128 MB of memory in the
machine.
I checked it again (by rebooting it and seeing its booting messages, stupid
The situation is as follows:
Physical memory is 128M, OS is FreeBSD 4.4.
My C++ simulation code mallocs large amount of memory. When running, I found
