Kernel + libc bug.  You need to log in directly as root (no "su",
no "sudo") and you must not have any ulimits set.  Even if you try
to set your ulimit to "unlimited" (and even if it shows "unlimited")
it is really 2GB.

You can also upgrade to 2.4.18-pre2+ or glibc-2.2 to fix this.

Cheers, Andreas
