[Samba] smb panic

[Chris Nighswonger]

Hi all,

Misc Info:

PDC:
Ubuntu 12.10 (Quantal)
Samba 3.6.6

File server:
Ubuntu 10.04.4 LTS
Sama 3.4.7

Winbindd on the file server panics every few days. It seems to
correspond to times when the PDC is restarted.

Nothing outstanding appears in the file server client log on the PDC.

Here is a few lines of the log from the file server winbindd log:

Any thoughts on what direction to walk it to troubleshoot this?

Kind Regards,
