If the bug has anything to do with Samba behaving incorrectly as a
server (like refusing to open a file) then the log files will probably
be very useful. Depending on the problem a log level of between 3 and
10 showing the problem may be appropriate. A higher level gives more
detail, but may use too much disk space.
