Regardless of any other limits, linux-2.4.1/kernel/exit.c:482-485 has:

asmlinkage long sys_exit(int error_code)
{
do_exit((error_code&0xff)<<8);
}

linux-2.4.1/kernel/exit.c:482-485 has the following, so even if
anything else passes more bits, only the low 8 get handled.

asmlinkage long sys_exit(int error_code)
{
do_exit((error_code&0xff)<<8);
}

Subject: what's wrong with wget?  It used to work! Is this a kernel problem?

I'm using RedHat 7.0 and wget now consistently
hangs on numerous ftp servers.

I'm really baffled as to why it's not working
because it works for people with other Linux
distributions, yet I tried the original binary
with RedHat 7.0 (wget 1.5.3) AND recompiled
the latest wget-1.6 and both still just hang!
The strange thing is that wget used to work
just fine only a few months ago when I was
using RedHat 6.2 with an older kernel version.

Curiously I have no problems downloading using
ncftpget.

Is anyone getting the same problem?

strace wget -m
ftp://ftp.netscape.com/pub/netscape6/english/6.0/unix/linux22/xpi/jre.xpi

The real fun starts in this program:

   /usr/src/linux-2.0.35/init/main.c

in the procedure

   start_kernel(void)

What comes before that is a lot of tricks to get the linux kernel into
memory, uncompressed, and so on.

Well... have you considered that you may have some really bad sectors on
your swap partition??

I don't understand you, SuSE Linux 6.0 has glibc2 as main libc.
What are your problems with it ?

Linux is like a Vorlon.  It is incredibly powerful, gives terse,
cryptic answers and has a lot of things going on in the background.
