Winbind crashing every minute

[KernelMatt]

I've just setup a FreeNas box on our network and joined it to our AD.
However every minute the winbindd service crashed out with a signal 6.

We're running an AD with 2003 and 2008R2 DCs and I've followed the steps described in this post:
http://forums.freenas.org/showthread.php?1931-2008R2-2003-mixed-domain
but it's had no effect.

I've tried setting the domain controler in Services->Active Dorectory Setttings to a 2003 dc and a 2008r2 dc but again it's had no effect.

I've setup other samba servers (running on Ubuntu) on the domain and haven't had a problem.

Straingly, despite these errors every minute, AD authentication seems to work so I've no idea why it's happening.

This is what's displayed in /var/log/messages

In the /var/log/samba/log.wb-<domain> file I've noticed this:

Does anyone have any ideas?

I have exactly the same issue,
