Hello!
Recently I moved some file shares from old server to new one with CentOS
5.2 and samba 3.0.32.
And yesterday we found that antivirus (nod32 ) installed on users
computers do strange thing-
it's often locks and locks files.
Here is part of log with debug level = 10

so opening files becomes very slow process.
I turned off kernel oplocks and all becomes OK.
Strange thing is that there was no such problem in on old SLES9 server
with samba 3.0.30 and on our RHEL server with samba 3.0.28 (and with
the same kernel version as CentOS).
Could you tell me- how do you think is it samba or kernel problem?
Thank you!
