[Samba] Samba and oplock_break errors (addition)

[Kestutis Saldziunas]

Sorry I have send not finished email accasionally...
So I repeat the email once again :)))


I have recently migrated from Novell Netware file server to Samba 2.2.0-15 with 15 users.
For couple days I wondered how could new my Samba server work so well !
However on next week users started complaining
that their computers hang for minutes and displays errors (not found *.dll
or fatal app error) when trying to start applications. Only Samba server
restarting solved problems. It is related with oplocks break, so I made shared directories for read only ( as it serves for application), but it not solved the problem.
Is any other solution ? Should I migrate to higher Samba version in order to keep oplocks funkctionality in Samba ?

One other interesting thing that in another branch also I installed Samba server with identical configuration, but there is no oplocks erros because in the branch works only 6 users.

Thanks in advance for responce.
