Directories show empty after some time ...

[axs at zurich.ibm.com]

Sorry that I will ask a kind of a vague question, but I don't really know
how to proceed at the moment:

Some of our Samba (1.9.18p10) users experience the following problem: they
map a drive to a Samba share (pointing into AFS, if that matters) and see
all files/dirs correctly after the password dialog. 'Some time' later (for
one user usually about one hour) they try to use the drive again and find
that the drive/dir looks empty. A disconnect and reconnect solves the
problem.
This problem is only with some users (Win95 and NT4) of the Samba server,
f.e. I can't reproduce it for me.

I don't see any problems in the log with loglevel=2, and I simply don't
know how to extract the important information from the log in the higher
loglevels :-(.

Any ideas are welcome on how I should proceed, what the problem could be
etc ...!!!

I append a log snipped, which was generated during one of this 'empty
directory' listings with loglevel=4, maybe the experts can tell something
from it:

(Can I learn somewhere, how to interpret this?)

Thank you very much!
