Hi.
On FreeBSD 6.2 i386 with 2GB of physical memory I can't allocate
more than 500Mb for my program.
I'm a new to FreeBSD. Is this limitatin is something known,
how do I overcome it ?
(On linuxes I can allocate arrays of size close to sum
of physical and swap memory, on similar machines)
Thank you and regards,
Dima.
$ top
...
Mem: 65M Active, 357M Inact, 142M Wired, 404K Cache, 112M Buf, 1437M Free
Swap: 4070M Total, 4070M Free
...
test code:
-------------------------------------------------------
#include<vector>
#include<boost/shared_array.hpp>
const unsigned M = 1024*1024;
const unsigned X = 510; // will fail with X > 510
int main() {
std::vector<char> huge_v1(X*M); // fails in both ways
// boost::shared_array<char> huge( new char[X*M] );
}
