Hello,

I can't seem to get my NetBSD-current kernel to swap/page.
The kernel is current as of 7/26 (supped on 7/27).
I have over 100 Meg of swap space, but I can't seem to use any of it.

Here's the story.  The following program runs out of VM

#include <stdio.h>

main(int argc, char** argv)
{
	char* p; char* s; char *e;
	p = malloc(1024*1024*atoi(argv[1]));
	if (!p) {
	    fprintf(stderr, "no memory\n");
	    exit(-1);
	}
	while (1) {
	    s = p; e = p + 1024*1024*atoi(argv[1]);
	    while (s < e) *s++ = *p;
	}
	    
}

synopsis:
chase@marvin>foo 8 &
[1] 392
chase@marvin>ps xu
USER       PID %CPU %MEM   VSZ  RSS TT  STAT STARTED       TIME COMMAND
chase      392 69.9 25.6  8208 8392 p2  R     4:20PM    0:03.66 foo 8 

(works fine consuming only 8 meg)

But note:

chase@marvin>pstat -s
Device      512-blocks     Used    Avail Capacity  Type
/dev/wd0b       262080    20680   241400     8%    Interleaved
chase@marvin>foo 16
no memory

I have 32Meg of physical RAM in the machine, here's the disktab (in
case that is relevant)

Any suggestions on what I could have done wrong?  I'd be happy to
provide the kernel config to anyone curious enough to want to see it.

Thanks!

Craig
