Please try to use the following compile options:
-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
Here a short testprogram:
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <sys/mman.h> /* mmap() is defined in this header */
#include <fcntl.h>
#include <error.h>
int main (int argc, char *argv[])
{
int fdin, fdout;
char *src, *dst;
struct stat statbuf;
if ((fdin = open (argv[1], O_RDONLY)) < 0) {
perror ("open error\n");
return(1);
}
if (fstat (fdin,&statbuf) < 0) {
printf ("fstat error\n");
return(1);
}
if ((src = mmap (0, statbuf.st_size, PROT_READ, MAP_SHARED, fdin, 0)) == (caddr_t) -1) {
perror ("mmap error for input\n");
return(1);
}
close (fdin);
return (0);
}
gcc -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -o test_mmap test_mmap.c
Please report the situation.

Subject: cache size limit
Hi,
i'm trying to set up NewsCache on a FreeBSD 6.1 Stable machine. (2800
Mhz Pentium 4 / 1024M RAM). If I try to run newscache as news/news
user and group the .db file never grows larger than 2048M (even if i
set the max cache size to 40gig+). If i run newscache as root/wheel
the same thing happens... but with a segfault, too...
Here's what I see in the log:
---
NewsCache[9219]: updating the overview database
failed(alt.binaries.blah.blah): NVContainer::make_current(): mmap
failed
kernel: pid 9219 (newscache), uid 0: exited on signal 11 (core dumped)
NewsCache[9192]: 9219 caught signal 11
---
I'm using the FreeBSD port version (Makefile states PORTVERSION= 1.2.r.6)
I tried to get a cvs snapshot, but it seems that the cvs password
listed on site doesn't work anymore.
Anyone could give me a hint, why should i do in order to get a full
update / bigger than 2048M?
PS
The file system is UFS (/dev/ad0s1a on / (ufs, local, soft-updates)
Thank You!
