I am running 1.5.2, with a generic kernel, on a machine with 256Meg of
ram.  Under bash, ulimit -m returns 250316 (kbytes).

Nonetheless, my scheme processes are being killed by out-of-memory
errors at 128M, even though top reports that the system has memory
to spare.

In fact, the following program

--------------------------

#include <stdio.h>

 int main()
 {
    while (1) { malloc(4096); }
 }

--------------------------

allocates 128M (according to top), and no more.



I would be most grateful if someone could explain this to me!  Can
the effective upper limit on process size be increased?



Thanks much,


D. Troeger
