Hi list, hi Jeremy,
I apologize for such a bad report, but I do not have any further
information and cannot reproduce.
I mounted a Samba share (data) using CIFS. Afterwards I was not able to read a
file (SLES10-i386-ISO/SLES-10-x86-CD1.iso) despite UNIX and Samba permission
allowed it. While trying to access this file, Samba ran into a panic action:

Why did Samba ran into that panic action?
If you need any further information, please feel free to ask!
Thanks in advance!
With kind regards,
