I've been on holiday, but my hope is to release some time in the next
week or two.

It will decrease performance, but add rudundency.  (You can setup
multi-master replication).

Do you need 2 servers?

If slapd crashes, then please file a bug with OpenLDAP.  slapd should
never crash, no matter how bad Samba behaves, and I know the OpenLDAP
crew are very keen to chase down any issues.

Odd.  I wonder what changed.

Can you figure out what point the smbd is stuck at when this happens?
Breaking the server with gdb might help.

Frankly, never use libnss_ldap instead of Winbind.  We wrote winbind
because libnss_ldap and pam_krb5 isn't enough for proper windows
interoperability.  It still astounds me how many folks think "it can't
be that hard, I don't need winbind", and then wonder why it is...
