[Samba] HELP: Samba server crashing on me

[Timothy Normand Miller]

For no reason that I can discover, my smb server has started crashing
on me.  I'm really hoping someone help me out with this.  This is the
relevant portion of the log:

Other things:

- I did try stopping and restarting the service
- I ran testparm, and it says my config is fine
