The following C program allocates slices of 10MB of memory until it is killed by the Out of Memory killer.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
int main() {
int counter = 0;
int slice_size = 10*1000*1000;
char c = 0;
while (1) {
char *assigned = malloc(slice_size);
memset(assigned, c, slice_size);
counter++;
printf("Managed to assign %d times %d\n", counter, slice_size);
usleep(100000)
}
}
Given that free -m (ran immediately after the program ran) reports 6450 MB of free memory
total used free shared buffers cached
Mem: 7583 1595 5988 0 0 462
-/+ buffers/cache: 1132 6450
Swap: 0 0 0
why does this program only manage to assign 623 times 10MB before it is killed?
Managed to assign 1 times 10000000
[..]
Managed to assign 622 times 10000000
Managed to assign 623 times 10000000
Killed
There seems to be a hole of about 220 MB between what I thought I could malloc and what I could actually malloc. It's not kernel memory: cat /proc/meminfo immediately after the program ran:

Some possible explanations:
There is memory that could be freed, and will be freed, if memory pressure slowly increases, but it hasn't yet been freed and isn't freed rapidly enough to cope with this program. I added the
usleepto try to provide some time. It doesn't seem to matterThe memory is being assigned, but the OOM killer prevents the shell from printing what it received from
printf. Again, I'd think theusleepprovides plenty of time to allow that.
OOM killer output:
