Hi Dermot,

> Can you determine what the user process is? smbstatus perhaps?
as long as the apw is opened, smbstatus says user "administrator". I 
controlled the pid with ps -ef and it said uid 1001. Also, smbd seems to 
run with normal user priviliges.

I did so, but the smb panic occured again, but the error messages 
"Unable to open new log file /var/log/samba/log.smbd: Permission denied
" disappeared.
For a test i set the permissions for all files and subdirectories in 
/var/lib/samba to 777, but this didn't solve the error.
When the panic occurs, samba was still able to create the queue in cups, 
but the smbd died before associating the queue with the uploaded printer 
driver.

Regards

Thorsten
