[Samba] smbd processes 99% cpu and end-user locks up (good gdb attached)

[Nathan Vidican]

I've got openldap-2.2.27 installed via FreeBSD ports-collection; made from 
source on this machine, I can quite easily swap it out for another version, any 
suggestions? - OpenLDAP.org lists 2.2.26 as the most 'stable' version, I have 
tried newer ones with little success before.

Do I need to re-compile samba after updating openldap? Does samba include 
updated source files/libraries from openldap, or does it just access system 
openldap libs as it appaears in the gdb output (ie: upgrade 
/usr/local/lib/libldap-2.2.so.7 vs upgrading openldap+samba too)
