>Description:
Utility rpc.statd shows itself as consuming 256MB of virtual
memory. Digging into its sources reveals it does an nmap of this amount
to hold a simple file of contactable sites. This is absurd. I reduced
the nmap size to a rational amount. FreeBSD 4.7-RELEASE.
Excerpt from /usr/src/sbin.usr/rpc.statd/file.c is included, with
my one line change.

>How-To-Repeat:
>Fix:
Excerpt from file.c
/* File now open. mmap() it, with a generous size to allow for */
/* later growth, where we will extend the file but not re-map it. */
status_info = (FileLayout *)
mmap(NULL, 0x1000, PROT_READ | PROT_WRITE, MAP_SHARED, status_fd, 0);
/*JRD was 256MB! mmap(NULL, 0x10000000, PROT_READ | PROT_WRITE, MAP_SHARED, s
tatus_fd, 0); */
if (status_info == (FileLayout *) MAP_FAILED)
warn("unable to mmap() status file");
