[Samba] Winbind dies redux

[Dimitri Yioulos]

All,

I fear I''ve become a pita with this, but windbind periodically dying 
on one of my machines is really starting to cause grief, and I have 
no idea what might be causing it, especially as the same config is 
used on several similar boxes which do not exhibit the problem.  
While I've posted the problem previously, I thought that maybe this  
latest log entry after winbind dies might help with finding the 
solution:

If anyone can help me out with this, I'd be most grateful.
