amd(8) aborting on file server running FBSD 6.3

[Lee Damon]

host in question is:
FreeBSD goose.ee.washington.edu 6.3-STABLE FreeBSD 6.3-STABLE #6: Wed 
Mar 26 17:03:35 PDT 2008 
root at goose.ee.washington.edu:/usr/obj/usr/src/sys/NIKOLA  i386


This box was recently updated to a release that was exactly the same 
source base as two other boxes I've been using for a month.  Upon 
upgrade amd(8) is now aborting shortly after launch (sometimes even 
before I can log in on the console there are references to missing amd 
process(es) in /var/log/messages).

I would really appreciate it if someone could take a look at the truss & 
gdb output at 
<http://ssli.ee.washington.edu/people/nomad/amd-crash1/truss.out> 
(181MB!) and 
<http://ssli.ee.washington.edu/people/nomad/amd-crash1/gdb.out> along 
with <https://ssli.ee.washington.edu/people/nomad/amd-crash1/amd.log> 
and see if they can give me a clue about what the problem is.  I also 
have a core file and a copy of the binary available though I'd prefer 
not to send that URL out to the world. :)

It looks like it might be related to nss_ldap.  I've removed and 
reinstalled all of the ldap ports with no success.

Any help with this would be greatly appreciated.  No one has home 
directories right now because this is the main homedir server in the lab.

thanks,
nomad
