Large data areas - how much can you malloc

One of the funny (in a tear-your-hair fashion) things with AIX is that it has so many process models, and no matter what they will give you trouble somehow.

One common issue for us is that we hit the default limit of 256 Mbyte data per process. And of course, our applications usually don't signal that they run out of memory, instead we get weird segmentation faults and other freaky stuff.

And of course, these issues do not surface often enough for this to be the first thing we think about. But everytime it does it makes me want to set MAXDATA for everything (which I of course won't do).
