Hello!
I have a problem with allocation memory in FreeBSD-3.2-RELEASE. This simple
program hungs my system:
------------------- begin program -----------------------------
#include <unistd.h>
#include <stdlib.h>
#define NALLOC 1000
#define SIZEALLOC 1024*1024
#define WAIT 100
void main()
{
char *p_mem;
int i, j;
if (fork() != 0) return;
for (i=0; i<NALLOC; i++) {
// usleep(WAIT);
p_mem = (char *)malloc(SIZEALLOC);
for (j=0; j<SIZEALLOC; j++) {
p_mem[j] = 0;
}
}
while (1);
}
------------------- begin program -----------------------------
I have a swap space about 100 M. After run this program, i can't write
something to my consoles -- system like hang system. But it answer for ping.
It may be my problem, but it may be kernel problem ;)
P.S. My English is not as well, as i want. If you have troubles with read my
letter, sorry.
Good luck,
Alec
