samba - May 2005 - Linux 2.4.29 w/ acl, joining domain, all system memory used up?!

I have Gentoo with 2.4.29 kernel installed on a 1.0Ghz Celeron. I 
patched the kernel for extended attributes and acl support. I compiled 
samba with acl, kerberos and ldap support. I am now trying to join my 
Windows 2000 domain.

I issed the following command, with these results:

--
hebe root # net ads join -U btimby
btimby's password:
Killed
--

And in my syslog:

--
hebe root # tail -n 2 /var/log/messages
May 25 08:39:58 hebe __alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
May 25 08:39:59 hebe VM: killing process net

Funny that it seems ALL my memory gets used up!
