oplock_break failed

[Michael Doerner]

Hi,

I am running Samba 2.0.3 on Linux Kernel 2.2.5 (SuSE 6.1) in a test
environment with a Win NT server (PDC), the Linux box taking over step by
step the file- and printserver tasks, and Win 95 clients. Samba is setup
with security=domain at this stage.

It just happened again what I have seen only a few times before. When I use
Outlook 98 on the Win95 machine and want to access the "personal folder
file" (which lives on the Linux box), Outlooks hangs for a while (30 sec.,
see below).

The following SMB log entries I find in the log file:

[1999/05/30 22:39:53, 0] smbd/service.c:make_connection(320)
  michael logged in as admin user (root privileges)

  michael logged in as admin user (root privileges)
[1999/05/30 22:40:34, 1] smbd/service.c:make_connection(488)

Hmm, I need a bit of help to understand what this oplock_break failed means
or where I will have to read about that?

Best regards,
