I wrote a test program that does malloc of 1K until it's running out of memory.

On a 2G machine with 1.8 gig free, it allocates up to 1G.

On a 3G machine with 2.1 gig free, it allocates up to 720Megs.

On a 3G machine with 2.6 Gig, it allocates up to 1G.

Explanation please?

Re: Maximum size of data segment

Under 4.25 the segments sizes possible are 64k and 1gig.  I'm not sure why one of your computers couldn't allocate up to
 the same potential as the other two.  It's hard to really know based on the information provided.
