I would like to know, what the oplock 'EXCLUSIVE+BATCH' exactly
means. Does anybody know a good manual about samba's oplocks?
Could it possibly cause oplock-trouble and even disconnections, if
a user is constantly logged in on one AD-workstations and also
frequently accesses network files from a WinXP+SP2 workstation (that is
not part of the AD-Domain) via credentials?
Nice regards, bbb
One of our AD-users is having severe problems with frequent
disconnections from the AD-Domain. I've noticed that the user has quite
a lot error messages, that look like this:
[2013/10/21 08:53:15.854203, 0]
Oplock break failed for file
-- replying anyway
There's also something strage about the users locked files in smbstatus
output: when any other user would use the oplock 'BATCH', the user with
the problems always uses 'EXCLUSIVE+BATCH'

The user with the disconnection-problems is constantly working on two
different workstations at the same time... unfortunately we have to use
an additional WinXP+SP2 workstation for a special software, we need. I'm
currently setting up a second account for this users - perhaps it will
help. This is not a support-request, just a question/discussion.
