Hi list, i'm have trouble with oplocks break failed for file xxx

I'm using samba running in ubuntu natty 11.04* with separate ldap server :

:~# dpkg -l | grep samba
ii* libcrypt-smbhash-perl********** 0.12-3**************************** generate LM/NT hash of a password for samba


ii* samba************************** 2:3.5.8~dfsg-1ubuntu2.2*********** SMB/CIFS file, print, and login server for Unix
ii* samba-common******************* 2:3.5.8~dfsg-1ubuntu2.2*********** common files used by both the Samba server and client


ii* samba-common-bin*************** 2:3.5.8~dfsg-1ubuntu2.2*********** common files used by both the Samba server and client
ii* samba-doc********************** 2:3.5.8~dfsg-1ubuntu2.2*********** Samba documentation



My problems is strange, when user open file(office file like excel, word) directly from server it is normal but whe user close that file it is extremely slow. But copy files from and to samba server is normal, just "stream" office file from server. Only some user have trouble like that, not all of user and some file like that not all of office file. It is very strange for me because just some user(2 user exactly from 100++ user) and some file office if i'm close that it is extremely slow not all office file.
