[Samba] Samba and oplock_break errors

[Kestutis Saldziunas]

Hello,

I have recently migrated from Novell Netware file server to Samba 2.2.0-15.
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 so






The black day log is such:

In the day beginning:

continiuos erros:

After I restarted server and till now I have to restart server periodically
each several days.
